UEbung macht den Meister - so ist es auch in der Mathematik. Dieses Buch enthalt rund 450 Aufgaben aus verschiedenen Themenbereichen der Analysis II, die der Leserin/dem Leser dieses Buches beim Selbststudium, der hauslichen Nacharbeit des Vorlesungsstoffes und der Klausurvorbereitung helfen sollen. Dabei ist das Buch als ein Begleitwerkzeug zu verstehen, das die eifrige Leserin/den eifrigen Leser beim eigenstandigen Entwickeln von Loesungen durch gezielte Hinweise und verstandliche Loesungen unterstutzen soll. Sollten bei der Bearbeitung der Aufgaben Probleme oder Fragen aufkommen, so kann der entsprechende Loesungshinweis im zweiten Teil des Buches nachgeschlagen werden. Die eigens entwickelte Loesung der Leserin/des Lesers kann dann im Teil Loesungen mit der detaillierten und verstandlich geschriebenen Loesung abgeglichen werden. Der letzte Teil dieses Buches enthalt funf UEbungsklausuren mit unterschiedlichem Umfang, Schwierigkeitsgrad und Fokus auf einzelne Resultate und Methoden aus der Analysis II, mit denen sich die Leserin/der Leser auf eine schriftliche Prufung vorbereiten kann. Da die Vorlesung Analysis II von Universitat zu Universitat mit teilweise sehr unterschiedlichen Schwerpunkten gehalten wird, ist es denkbar, dass einige Themenbereich, die in diesem Buch behandelt werden, eher in die Analysis III oder in ein anderes Fach eingeordnet werden koennen. Dieses Buch koennte damit also auch fur Leserinnen/Leser von Interesse sein, die gerade die Vorlesung Vektoranalysis, Mass- und Integrationstheorie, Funktionalanalysis oder gewoehnliche Differentialgleichungen besuchen.

A New World of Geometry Awaits Your Discovery! The last stone falls out ... a rush of ancient air ... the glint of gold ... the tingle of discovery ... When explorers first opened the tombs of the ancient pharaohs, they knew that they had discovered something wonderful. That feeling, that same passionate sense of discovery, is one of the most powerful educational tools a text can deliver. Geometry by Discovery is an exciting new approach to geometry. This ground-breaking text taps the pedagogical value of discovery to help students stretch their geometric perspective and hone their geometric intuition. It actively engages students in solving mathematical problems, and empowers them to be successful problem-solvers and discoverers of mathematical ideas.

Inspiring popular video games like Tetris while contributing to the study of combinatorial geometry and tiling theory, polyominoes have continued to spark interest ever since their inventor, Solomon Golomb, introduced them to puzzle enthusiasts several decades ago. In this fully revised and expanded edition of his landmark book, the author takes a new generation of readers on a mathematical journey into the world of the deceptively simple polyomino. Golomb incorporates important, recent developments, and poses problems, inviting the reader to play with and develop an understanding of the extraordinary properties of polyominoes.

This classic work is now available in an unabridged paperback edition. The Second Edition retains all the characterisitcs that made the first edition so popular: brilliant exposition, the flexibility permitted by relatively self-contained chapters, and broad coverage ranging from topics in the Euclidean plane, to affine geometry, projective geometry, differential geometry, and topology. The Second Edition incorporates improvements in the text and in some proofs, takes note of the solution of the 4-color map problem, and provides answers to most of the exercises.

Like Descartes and Pascal, Hans Hahn (1879-1934) was both an eminent mathematician and a highly influential philosopher. He founded the Vienna Circle and was the teacher of both Kurt Goedel and Karl Popper. His seminal contributions to functional analysis and general topology had a huge impact on the development of modern analysis. Hahn's passionate interest in the foundations of mathematics, vividly described in Sir Karl Popper's foreword (which became his last essay), had a decisive influence upon Goedel. Like Freud, Musil and Schoenberg, Hahn became a pivotal figure in the feverish intellectual climate of Vienna between the two wars. Volume 1: The first volume of Hahn's Collected Works contains his path-breaking contributions to functional analysis, the theory of curves, and ordered groups. These papers are commented on by Harro Heuser, Hans Sagan, and Laszlo Fuchs. Volume 2: The second volume deals with functional analysis, real analysis and hydrodynamics. The commentaries are written by Wilhelm Frank, Davis Preiss, and Alfred Kluwick. Volume 3: In the third volume, Hahn's writings on harmonic analysis, measure and integration, complex analysis and philosophy are collected and commented on by Jean-Pierre Kahane, Heinz Bauer, Ludger Kaup, and Christian Thiel. This volume also contains excerpts of Hahn's letters and accounts by his students and colleagues.

Questa seconda edizione, oltre a semplificare alcune dimostrazioni, presenta una sostanziale riscrittura della parte sui rivestimenti e l'aggiunta di ulteriori esempi; il numero complessivo di esercizi proposti stato portato a 500 ed il numero di quelli svolti a 120.

Vektorbundel stellen eine faszinierende Verbindung von Algebra und Topologie dar. Die bekanntesten Beispiele, das Mobiusband und das Tangentialbundel, veranschaulichen schon unmittelbar zwei Hauptaspekte.

Einmal geben Vektorbundel Hinweise auf die Gestalt eines Raumes - so deutet ein Mobiusband auf das Vorhandensein eines "Loches" hin -, andererseits lassen sich geometrische Objekte wie Mannigfaltigkeiten durch Vektorbundel linearisieren. Durch diese Nahe zur Geometrie hat die Vektorbundeltheorie nicht nur zahlreiche Anwendungen, so kann man beispielsweise schon mit geringen Voraussetzungen bis zur Losung des Divisionsalgebrenproblems vordringen, sondern sie ist auch in vielen Gebieten der Mathematik Teil der grundlegenden Sprache. Der Text beginnt mit einer ausfuhrlichen nur auf geringe Voraussetzungen aufbauenden Darstellung der Grundlagen. Er fuhrt dann uber das als zentrales Thema behandelte Schnittproblem bis zu einer Herleitung und Hintergrunddiskussion des Vektorfeldsatzes und des entsprechenden Satzes fur stabile Bundel uber Spharen. Er ist gedacht fur alle, die die abstrakten Ideen und Techniken der algebraischen Topologie an ganz konkreten Situationen erproben, erlernen oder anwenden mochten."

Wie bewegt sich ein Massenpunkt in einem Gebiet, an dessen Rand er elastisch zuruckprallt? Welchen Weg nimmt ein Lichtstrahl in einem Gebiet mit ideal reflektierenden Randern? Anhand dieser und ahnlicher Fragen stellt das vorliegende Buch Zusammenhange zwischen Billard und Differentialgeometrie, klassischer Mechanik sowie geometrischer Optik her. Dabei beschaftigt sich das Buch unter anderem mit dem Variationsprinzip beim mathematischen Billard, der symplektischen Geometrie von Lichtstrahlen, der Existenz oder Nichtexistenz von Kaustiken, periodischen Billardtrajektorien und dem Mechanismus fur Chaos bei der Billarddynamik. Erganzend wartet dieses Buch mit einer beachtlichen Anzahl von Exkursen auf, die sich verwandten Themen widmen, darunter der Vierfarbensatz, die mathematisch-physikalische Beschreibung von Regenbogen, der poincaresche Wiederkehrsatz, Hilberts viertes Problem oder der Schliessungssatz von Poncelet.

Wahrend einer Konferenz zum "Jiidischen Nietzscheanismus" 1995 in Greifs wald hatte mich EGBERT BRIESKORN eingeladen, in der Edition der Gesam melten Werke FELIX HAUSDORFFS dessen philosophische Schriften mit einer Einleitung herauszugeben. FELIX HAUSDORFF hatte darin eng an NIETZSCHE angeschlossen, und er hatte in Greifswald sein erstes Ordinariat fUr Mathematik erhalten - ich sagte spontan und, wie sich bald herausstellen soUte, leichtsinnig ja. Statt nur mit einer kurzen Einleitung hatte ich es bald auch mit langwieri gen Erschlief&ungen des Werks und seiner Kommentierung zu tun. Doch je mehr ich mich in FELIX HAUSDORFFS Schriften einarbeitete, desto mehr notigten sie mir Respekt ab: in ihrer Klarheit, ihrer Redlichkeit, ihrer vornehmen Beschei denheit, ihrer gedanklichen Selbstandigkeit und vor allem in ihrer erstaunlichen Aktualitat. Vielleicht ist nach iiber hundert Jahren nun die Zeit gekommen, in der sie fiir die philosophische Orientierung so fruchtbar werden konnen, wie sie es verdienen. Bei der Kommentierung haben viele helfende Hande mitgewirkt. Mein Dank gilt zuerst den studentischen und wissenschaftlichen Hilfskraften: MIRKO GRON DER und KATRIN STELTER haben die Hauptarbeit in der Recherchierung der Belege iibernommen, JUDITH KARLA und TANJA SCHMIDT eine Vielzahl von Nachweisen beigesteuert, WOLFGANG SCHNEIDER und RALF WITZLER an den Vorarbeiten mitgewirkt. Doz. Dr. REINHARD PESTER (friiher Greifswald, jetzt Berlin) hat uns bei den Nachweisen zu LOTZE, Prof. Dr. MARTIN HOSE (frii her Greifswald, jetzt Miinchen) bei Zitaten aus der griechischen Literatur, Prof. Dr. GISELA FEBEL (friiher Stuttgart, jetzt Bremen) bei Zitaten aus der franzosischen Literatur, Prof. Dr. WALTER ERHART, Prof. Dr."

Groups as abstract structures were first recognized by mathematicians in the nineteenth century. Groups are, of course, sets given with appropriate "multiplications," and they are often given together with actions on interesting geometric objects. But groups are also interesting geometric objects by themselves. More precisely, a finitely-generated group can be seen as a metric space, the distance between two points being defined "up to quasi-isometry" by some "word length," and this gives rise to a very fruitful approach to group theory.
In this book, Pierre de la Harpe provides a concise and engaging introduction to this approach, a new method for studying infinite groups via their intrinsic geometry that has played a major role in mathematics over the past two decades. A recognized expert in the field, de la Harpe uses a hands-on presentation style, illustrating key concepts of geometric group theory with numerous concrete examples.
The first five chapters present basic combinatorial and geometric group theory in a unique way, with an emphasis on finitely-generated versus finitely-presented groups. In the final three chapters, de la Harpe discusses new material on the growth of groups, including a detailed treatment of the "Grigorchuk group," an infinite finitely-generated torsion group of intermediate growth which is becoming more and more important in group theory. Most sections are followed by exercises and a list of problems and complements, enhancing the book's value for students; problems range from slightly more difficult exercises to open research questions in the field. An extensive list of references directs readers to more advanced results as well as connectionswith other subjects.

Starting from the foundations, the author presents an almost entirely
self-contained treatment of differentiable spaces of nonpositive
curvature, focusing on the symmetric spaces in which every geodesic lies
in a flat Euclidean space of dimension at least two. The book builds to
a discussion of the Mostow Rigidity Theorem and its generalizations, and
concludes by exploring the relationship in nonpositively curved spaces
between geometric and algebraic properties of the fundamental group.
This introduction to the geometry of symmetric spaces of non-compact
type will serve as an excellent guide for graduate students new to the
material, and will also be a useful reference text for mathematicians
already familiar with the subject.

This volume presents lecture notes based on the author's courses on Lie algebras and the solution of Hilbert's fifth problem. In chapter 1, "Lie Algebras," the structure theory of semi-simple Lie algebras in characteristic zero is presented, following the ideas of Killing and Cartan. Chapter 2, "The Structure of Locally Compact Groups," deals with the solution of Hilbert's fifth problem given by Gleason, Montgomery, and Zipplin in 1952.

Aus den Rezensionen: "Was das Buch vor allem auszeichnet, ist die unkonventionelle Darstellungsweise. Hier wird Mathematik nicht im trockenen Definition-Satz-Beweis-Stil geboten, sondern sie wird dem Leser pointiert und mit viel Humor schmackhaft gemacht. In ungew hnlich fesselnder Sprache geschrieben, ist die Lekt re dieses Buches auch ein belletristisches Vergn gen. Fast 200 sehr instruktive und sch ne Zeichnungen unterst tzen das Verst ndnis, motivieren die behandelten Aussagen, modellieren die tragenden Beweisideen heraus. Ungew hnlich ist auch das Register, das unter jedem Stichwort eine Kurzdefinition enth lt und somit umst ndliches Nachschlagen erspart."

An undergraduate introduction to the fundamentals of topology - engagingly written, filled with helpful insights, complete with many stimulating and imaginative exercises to help students develop a solid grasp of the subject.

This invaluable book is based on the notes of a graduate course on differential geometry which the author gave at the Nankai Institute of Mathematics. It consists of two parts: the first part contains an introduction to the geometric theory of characteristic classes due to Shiing-shen Chern and Andre Weil, as well as a proof of the Gauss-Bonnet-Chern theorem based on the Mathai-Quillen construction of Thom forms; the second part presents analytic proofs of the Poincare-Hopf index formula, as well as the Morse inequalities based on deformations introduced by Edward Witten.

Uncover the Useful Interactions of Fixed Point Theory with Topological Structures Nonlinear Functional Analysis in Banach Spaces and Banach Algebras: Fixed Point Theory under Weak Topology for Nonlinear Operators and Block Operator Matrices with Applications is the first book to tackle the topological fixed point theory for block operator matrices with nonlinear entries in Banach spaces and Banach algebras. The book provides researchers and graduate students with a unified survey of the fundamental principles of fixed point theory in Banach spaces and algebras. The authors present several extensions of Schauder's and Krasnosel'skii's fixed point theorems to the class of weakly compact operators acting on Banach spaces and algebras, particularly on spaces satisfying the Dunford-Pettis property. They also address under which conditions a 2x2 block operator matrix with single- and multi-valued nonlinear entries will have a fixed point. In addition, the book describes applications of fixed point theory to a wide range of diverse equations, including transport equations arising in the kinetic theory of gas, stationary nonlinear biological models, two-dimensional boundary-value problems arising in growing cell populations, and functional systems of integral equations. The book focuses on fixed point results under the weak topology since these problems involve the loss of compactness of mappings and/or the missing geometric and topological structure of their underlying domain.

This book is an elementary introduction to geometric topology and its applications to chemistry, molecular biology, and cosmology. It does not assume any mathematical or scientific background, sophistication, or even motivation to study mathematics. It is meant to be fun and engaging while drawing students in to learn about fundamental topological and geometric ideas. Though the book can be read and enjoyed by nonmathematicians, college students, or even eager high school students, it is intended to be used as an undergraduate textbook. The book is divided into three parts corresponding to the three areas referred to in the title. Part 1 develops techniques that enable two- and three-dimensional creatures to visualize possible shapes for their universe and to use topological and geometric properties to distinguish one such space from another. Part 2 is an introduction to knot theory with an emphasis on invariants. Part 3 presents applications of topology and geometry to molecular symmetries, DNA, and proteins. Each chapter ends with exercises that allow for better understanding of the material. The style of the book is informal and lively. Though all of the definitions and theorems are explicitly stated, they are given in an intuitive rather than a rigorous form, with several hundreds of figures illustrating the exposition. This allows students to develop intuition about topology and geometry without getting bogged down in technical details.

Cohomology operations are at the center of a major area of activity in algebraic topology. This technique for supplementing and enriching the algebraic structure of the cohomology ring has been instrumental to important progress in general homotopy theory and in specific geometric applications. For both theoretical and practical reasons, the formal properties of families of operations have received extensive analysis.
This text focuses on the single most important sort of operations, the Steenrod squares. It constructs these operations, proves their major properties, and provides numerous applications, including several different techniques of homotopy theory useful for computation. In the later chapters, the authors place special emphasis on calculations in the stable range. The text provides an introduction to methods of Serre, Toda, and Adams, and carries out some detailed computations. Prerequisites include a solid background in cohomology theory and some acquaintance with homotopy groups.

This book provides the theory for stratified spaces, along with important examples and applications, that is analogous to the surgery theory for manifolds. In the first expository account of this field, Weinberger provides topologists with a new way of looking at the classification theory of singular spaces with his original results.
Divided into three parts, the book begins with an overview of modern high-dimensional manifold theory. Rather than including complete proofs of all theorems, Weinberger demonstrates key constructions, gives convenient formulations, and shows the usefulness of the technology. Part II offers the parallel theory for stratified spaces. Here, the topological category is most completely developed using the methods of "controlled topology." Many examples illustrating the topological invariance and noninvariance of obstructions and characteristic classes are provided. Applications for embeddings and immersions of manifolds, for the geometry of group actions, for algebraic varieties, and for rigidity theorems are found in Part III.
This volume will be of interest to topologists, as well as mathematicians in other fields such as differential geometry, operator theory, and algebraic geometry.
