This lecture notes volume presents significant contributions from
the "Algebraic Geometry and Number Theory" Summer School, held at
Galatasaray University, Istanbul, June 2-13, 2014. It addresses
subjects ranging from Arakelov geometry and Iwasawa theory to
classical projective geometry, birational geometry and equivariant
cohomology. Its main aim is to introduce these contemporary
research topics to graduate students who plan to specialize in the
area of algebraic geometry and/or number theory. All contributions
combine main concepts and techniques with motivating examples and
illustrative problems for the covered subjects. Naturally, the book
will also be of interest to researchers working in algebraic
geometry, number theory and related fields.
This volume presents easy-to-understand yet surprising properties
obtained using topological, geometric and graph theoretic tools in
the areas covered by the Geometry Conference that took place in
Mulhouse, France from September 7-11, 2014 in honour of Tudor
Zamfirescu on the occasion of his 70th anniversary. The
contributions address subjects in convexity and discrete geometry,
in distance geometry or with geometrical flavor in combinatorics,
graph theory or non-linear analysis. Written by top experts, these
papers highlight the close connections between these fields, as
well as ties to other domains of geometry and their reciprocal
influence. They offer an overview on recent developments in
geometry and its border with discrete mathematics, and provide
answers to several open questions. The volume addresses a large
audience in mathematics, including researchers and graduate
students interested in geometry and geometrical problems.
This book collects the scientific contributions of a group of
leading experts who took part in the INdAM Meeting held in Cortona
in September 2014. With combinatorial techniques as the central
theme, it focuses on recent developments in configuration spaces
from various perspectives. It also discusses their applications in
areas ranging from representation theory, toric geometry and
geometric group theory to applied algebraic topology.
This volume, following in the tradition of a similar 2010
publication by the same editors, is an outgrowth of an
international conference, "Fractals and Related Fields II," held in
June 2011. The book provides readers with an overview of
developments in the mathematical fields related to fractals,
including original research contributions as well as surveys from
many of the leading experts on modern fractal theory and
applications. The chapters cover fields related to fractals such
as: *geometric measure theory *ergodic theory *dynamical systems
*harmonic and functional analysis *number theory *probability
theory Further Developments in Fractals and Related Fields is aimed
at pure and applied mathematicians working in the above-mentioned
areas as well as other researchers interested in discovering the
fractal domain. Throughout the volume, readers will find
interesting and motivating results as well as new avenues for
further research.
This book summarizes the author's lifetime achievements, offering
new perspectives and approaches in the field of metal cutting
theory and its applications. The topics discussed include
Non-Euclidian Geometry of Cutting Tools, Non-free Cutting Mechanics
and Non-Linear Machine Tool Dynamics, applying non-linear
science/complexity to machining, and all the achievements and their
practical significance have been theoretically proved and
experimentally verified.
Exploring the interplay between deep theory and intricate
computation, this volume is a compilation of research and survey
papers in number theory, written by members of the Women In Numbers
(WIN) network, principally by the collaborative research groups
formed at Women In Numbers 3, a conference at the Banff
International Research Station in Banff, Alberta, on April 21-25,
2014. The papers span a wide range of research areas: arithmetic
geometry; analytic number theory; algebraic number theory; and
applications to coding and cryptography. The WIN conference series
began in 2008, with the aim of strengthening the research careers
of female number theorists. The series introduced a novel
research-mentorship model: women at all career stages, from
graduate students to senior members of the community, joined forces
to work in focused research groups on cutting-edge projects
designed and led by experienced researchers. The goals for Women In
Numbers 3 were to establish ambitious new collaborations between
women in number theory, to train junior participants about topics
of current importance, and to continue to build a vibrant community
of women in number theory. Forty-two women attended the WIN3
workshop, including 15 senior and mid-level faculty, 15 junior
faculty and postdocs, and 12 graduate students.
The author defines "Geometric Algebra Computing" as the
geometrically intuitive development of algorithms using geometric
algebra with a focus on their efficient implementation, and the
goal of this book is to lay the foundations for the widespread use
of geometric algebra as a powerful, intuitive mathematical language
for engineering applications in academia and industry. The related
technology is driven by the invention of conformal geometric
algebra as a 5D extension of the 4D projective geometric algebra
and by the recent progress in parallel processing, and with the
specific conformal geometric algebra there is a growing community
in recent years applying geometric algebra to applications in
computer vision, computer graphics, and robotics. This book is
organized into three parts: in Part I the author focuses on the
mathematical foundations; in Part II he explains the interactive
handling of geometric algebra; and in Part III he deals with
computing technology for high-performance implementations based on
geometric algebra as a domain-specific language in standard
programming languages such as C++ and OpenCL. The book is written
in a tutorial style and readers should gain experience with the
associated freely available software packages and applications. The
book is suitable for students, engineers, and researchers in
computer science, computational engineering, and mathematics.
This book deals with fractals in understanding problems encountered
in earth science, and their solutions. It starts with an analysis
of two classes of methods (homogeneous fractals random models, and
homogeneous source distributions or "one point" distributions)
widely diffused in the geophysical community, especially for
studying potential fields and their related source distributions.
Subsequently, the use of fractals in potential fields is described
by scaling spectral methods for estimation of curie depth. The book
also presents an update of the use of the fractal concepts in
geological understanding of faults and their significance in
geological modelling of hydrocarbon reservoirs. Geophysical well
log data provide a unique description of the subsurface lithology;
here, the Detrended Fluctuation Analysis technique is presented in
case studies located off the west-coast of India. Another important
topic is the fractal model of continuum percolation which
quantitatively reproduce the flow path geometry by applying the
Poiseuille's equation. The pattern of fracture heterogeneity in
reservoir scale of natural geological formations can be viewed as
spatially distributed self-similar tree structures; here, the
authors present simple analytical models based on the medium
structural characteristics to explain the flow in natural
fractures. The Fractal Differential Adjacent Segregation (F-DAS) is
an unconventional approach for fractal dimension estimation using a
box count method. The present analysis provides a better
understanding of variability of the system (adsorbents - adsorbate
interactions). Towards the end of book, the authors discuss
multi-fractal scaling properties of seismograms in order to
quantify the complexity associated with high-frequency seismic
signals. Finally, the book presents a review on fractal methods
applied to fire point processes and satellite time-continuous
signals that are sensitive to fire occurrences.
The present volume contains invited talks of 11th biennial
conference on "Emerging Mathematical Methods, Models and Algorithms
for Science and Technology". The main message of the book is that
mathematics has a great potential to analyse and understand the
challenging problems of nanotechnology, biotechnology, medical
science, oil industry and financial technology. The book highlights
all the features and main theme discussed in the conference. All
contributing authors are eminent academicians, scientists,
researchers and scholars in their respective fields, hailing from
around the world.
This book contains a collection of papers presented at the 2nd
Tbilisi Salerno Workshop on Mathematical Modeling in March 2015.
The focus is on applications of mathematics in physics,
electromagnetics, biochemistry and botany, and covers such topics
as multimodal logic, fractional calculus, special functions,
Fourier-like solutions for PDE's, Rvachev-functions and linear
dynamical systems. Special chapters focus on recent uniform
analytic descriptions of natural and abstract shapes using the
Gielis Formula. The book is intended for a wide audience with
interest in application of mathematics to modeling in the natural
sciences.
These papers survey the developments in General Topology and the
applications of it which have taken place since the mid 1980s. The
book may be regarded as an update of some of the papers in the
Handbook of Set-Theoretic Topology (eds. Kunen/Vaughan,
North-Holland, 1984), which gives an almost complete picture of the
state of the art of Set Theoretic Topology before 1984. In the
present volume several important developments are surveyed that
surfaced in the period 1984-1991.
This volume may also be regarded as a partial update of Open
Problems in Topology (eds. van Mill/Reed, North-Holland, 1990).
Solutions to some of the original 1100 open problems are discussed
and new problems are posed.
Everyone knows what a triangle is, yet very few people appreciate
that the common three-sided figure holds many intriguing "secrets."
For example, if a circle is inscribed in any random triangle and
then three lines are drawn from the three points of tangency to the
opposite vertices of the triangle, these lines will always meet at
a common point - no matter what the shape of the triangle. This and
many more interesting geometrical properties are revealed in this
entertaining and illuminating book about geometry. Flying in the
face of the common impression that mathematics is usually dry and
intimidating, this book proves that this sometimes-daunting,
abstract discipline can be both fun and intellectually stimulating.
The authors, two veteran math educators, explore the multitude of
surprising relationships connected with triangles and show some
clever approaches to constructing triangles using a straightedge
and a compass. Readers will learn how they can improve their
problem-solving skills by performing these triangle constructions.
The lines, points, and circles related to triangles harbor
countless surprising relationships that are presented here in a
very engaging fashion.
Requiring no more than a knowledge of high school mathematics and
written in clear and accessible language, this book will give all
readers a new insight into some of the most enjoyable and
fascinating aspects of geometry.
This book presents some of the most important aspects of rigid
geometry, namely its applications to the study of smooth algebraic
curves, of their Jacobians, and of abelian varieties - all of them
defined over a complete non-archimedean valued field. The text
starts with a survey of the foundation of rigid geometry, and then
focuses on a detailed treatment of the applications. In the case of
curves with split rational reduction there is a complete analogue
to the fascinating theory of Riemann surfaces. In the case of
proper smooth group varieties the uniformization and the
construction of abelian varieties are treated in detail. Rigid
geometry was established by John Tate and was enriched by a formal
algebraic approach launched by Michel Raynaud. It has proved as a
means to illustrate the geometric ideas behind the abstract methods
of formal algebraic geometry as used by Mumford and Faltings. This
book should be of great use to students wishing to enter this
field, as well as those already working in it.
The main focus of this volume is on the problem of describing the
automorphism groups of affine and projective varieties, a classical
subject in algebraic geometry where, in both cases, the
automorphism group is often infinite dimensional. The collection
covers a wide range of topics and is intended for researchers in
the fields of classical algebraic geometry and birational geometry
(Cremona groups) as well as affine geometry with an emphasis on
algebraic group actions and automorphism groups. It presents
original research and surveys and provides a valuable overview of
the current state of the art in these topics. Bringing together
specialists from projective, birational algebraic geometry and
affine and complex algebraic geometry, including Mori theory and
algebraic group actions, this book is the result of ensuing talks
and discussions from the conference "Groups of Automorphisms in
Birational and Affine Geometry" held in October 2012, at the CIRM,
Levico Terme, Italy. The talks at the conference highlighted the
close connections between the above-mentioned areas and promoted
the exchange of knowledge and methods from adjacent fields.
Issues of matching and searching on elementary discrete structures arise pervasively in computer science and many of its applications, and their relevance is expected to grow as information is amassed and shared at an accelerating pace. Several algorithms were discovered as a result of these needs, which in turn created the subfield of Pattern Matching. This book provides an overview of the current state of Pattern Matching as seen by specialists who have devoted years of study to the field. It covers most of the basic principles and presents material advanced enough to faithfully portray the current frontier of research. As a result of these recent advances, this is the right time for a book that brings together information relevant to both graduate students and specialists in need of an in-depth reference.
This book proposes new notions of coherent geometric structure.
Fractal patterns have emerged in many contexts, but what exactly is
a "pattern" and what is not? How can one make precise the
structures lying within objects and the relationships between them?
The foundations laid herein provide a fresh approach to a familiar
field. From this emerges a wide range of open problems, large and
small, and a variety of examples with diverse connections to other
parts of mathematics. One of the main features of the present text
is that the basic framework is completely new. This makes it easier
for people to get into the field. There are many open problems,
with plenty of opportunities that are likely to be close at hand,
particularly as concerns the exploration of examples. On the other
hand the general framework is quite broad and provides the
possibility for future discoveries of some magnitude. Fractual
geometries can arise in many different ways mathematically, but
there is not so much general language for making comparisons. This
book provides some tools for doing this, and a place where
researchers in different areas can find common ground and basic
information.
