From the Preface: “There are three volumes. The first one contains a curriculum vitae, a «Brève Analyse des Travaux» and a Iist of publications, including books and seminars. In addition the volume contains all papers of H. Cartan on analytic functions published before 1939. The other papers on analytic functions, e.g. those on Stein manifolds and coherent sheaves, make up the second volume. The third volume contains, with a few exceptions, all further papers of H. Cartan; among them is a reproduction of exposés 2 to 11 of his 1954/55 Seminar on Eilenberg-MacLane algebras. Each volume is arranged in chronological order. The reader should be aware that these volumes do not fully reflect H. Cartan's work, a large part of which is also contained in his fifteen ENS-Seminars (1948-1964) and in his book "Homological Algebra" with S. Eilenberg... Still, we trust that mathematicians throughout the world will welcome the availability of the "Oeuvres" of a mathematician whose writing and teaching has had such an influence on our generation.�

Mathematics has a certain mystique, for it is pure and ex- act, yet demands remarkable creativity. This reputation is reinforced by its characteristic abstraction and its own in- dividual language, which often disguise its origins in and connections with the physical world. Publishing mathematics, therefore, requires special effort and talent. Heinz G-tze, who has dedicated his life to scientific pu- blishing, took up this challenge with his typical enthusi- asm. This Festschrift celebrates his invaluable contribu- tions to the mathematical community, many of whose leading members he counts among his personal friends. The articles, written by mathematicians from around the world and coming from diverse fields, portray the important role of mathematics in our culture. Here, the reflections of important mathematicians, often focused on the history of mathematics, are collected, in recognition of Heinz G-tze's life-longsupport of mathematics.

When this book was written, methods of algebraic topology had caused revolutions in the world of pure algebra. To clarify the advances that had been made, Cartan and Eilenberg tried to unify the fields and to construct the framework of a fully fledged theory. The invasion of algebra had occurred on three fronts through the construction of cohomology theories for groups, Lie algebras, and associative algebras. This book presents a single homology (and also cohomology) theory that embodies all three; a large number of results is thus established in a general framework. Subsequently, each of the three theories is singled out by a suitable specialization, and its specific properties are studied.

The starting point is the notion of a module over a ring. The primary operations are the tensor product of two modules and the groups of all homomorphisms of one module into another. From these, "higher order" derived of operations are obtained, which enjoy all the properties usually attributed to homology theories. This leads in a natural way to the study of "functors" and of their "derived functors."

This mathematical masterpiece will appeal to all mathematicians working in algebraic topology.

fuhrenden Mathematiker des 19. Jahrhunderts und einem der fiihrenden Geister der Friedrich-Wilhelms-Universit't zu Berlin in ihrer Glanzzeit, der zweiten H?lfte des 19. Jahrhunderts. WeierstraB war also ein Kollege von Paul Dubois Reymond, von Helmholtz, von Mommsen und Virchow. Karl WeierstraB ist ein Kind unseres Landes Nordrhein-Westfalen. Er wurde am 31. Oktober 1815 in Ostenfelde, Kreis Warendorf, also im Miinsterland, geboren. Seinen starken westf?lischen Akzent und seine politischen Auffassungen, mit denen er sich in der damaligen Zeit in PreuBen zu einer Minderheit rechnete, hat er niemals verleugnet. Er ist immer ein Westfale geblieben. Die Familie seines Vaters stammt aus Mettmann, also aus der unmittelbaren N?he dieser Stadt. So haben wir alle Griinde, seiner hier zu gedenken. Die groBe Zeit von WeierstraB liegt in den siebziger und achtziger Jahren des vorigen Jahrhunderts. Er galt damals schlechtweg als die Autorit't fur Strenge in den mathematischen SchluBweisen. Er war im Ausland, in einer Zeit, in der internationale wissenschaftliche Beziehungen sehr viel schwieriger waren als heute, ebenso angesehen wie in Deutschland.

Addressed to 2nd- and 3rd-year students, this work by a world-famous teacher skillfully spans the pure and applied branches, so that applied aspects gain in rigor while pure mathematics loses none of its dignity. Equally essential as a text, a reference, or simply as a brilliant mathematical exercise. 1971 edition.
