Group Cohomology and Algebraic Cycles Summary

Group Cohomology and Algebraic Cycles by Burt Totaro (University of California, Los Angeles)

Group cohomology reveals a deep relationship between algebra and topology, and its recent applications have provided important insights into the Hodge conjecture and algebraic geometry more broadly. This book presents a coherent suite of computational tools for the study of group cohomology and algebraic cycles. Early chapters synthesize background material from topology, algebraic geometry, and commutative algebra so readers do not have to form connections between the literatures on their own. Later chapters demonstrate Peter Symonds's influential proof of David Benson's regularity conjecture, offering several new variants and improvements. Complete with concrete examples and computations throughout, and a list of open problems for further study, this book will be valuable to graduate students and researchers in algebraic geometry and related fields.

Group Cohomology and Algebraic Cycles Reviews

'The author is one of the world experts on the Chow ring of algebraic cycles on the classifying space of an algebraic group and its interplay with the classical mod p cohomology ring. With a focus on finite groups, this text develops in parallel the theory of these two important families of rings. Very recent results about deep structural properties are presented here for the first time in book form, including, notably, Symonds's calculation of the CastelnuovoMumford regularity of group cohomology and its consequences. Some results about group cohomology are improvements on the literature, and many of the parallel results about Chow rings are new. The book is recommended for advanced students and researchers interested in seeing some of the lovely ways in which representation theory, algebraic topology, algebraic geometry, and commutative algebra fruitfully interact.' Nicholas Kuhn, University of Virginia
'This attractively written book provides a very readable and up-to-date account of the cohomology of groups. The emphasis is on the geometric point of view provided by the Chow ring of the classifying space. A particularly nice feature is that Symonds's recent proof of the regularity conjecture and several of its generalizations are discussed in detail.' David J. Benson, University of Aberdeen
'Cohomology of groups is usually developed algebraically via resolutions, and topologically via classifying spaces. This unique and attractively written book develops the subject from the point of view of algebraic geometry The book is full of computational examples that make accessible what could have been a very abstract subject. It is written at a level that could be used for a graduate course in cohomology of groups.' Mathematical Reviews
