Representation Theory and Complex Geometry Издательство: Birkhauser Boston, 1997 г Твердый переплет, 512 стр ISBN 0817637923 Язык: Английский инфо 11768i.

This volume is an attempt to provide an overview of some of the recent advances in representation theory from a geometric standpoint A geometrically-oriented treatment is very timely and has long been desiredаюъюе, especially since the discovery of D-modules in the early '80s and the quiver approach to quantum groups in the early '90s The first half of the book fills the gap between the standard knowledge of a beginner in Lie theory and the much wider background needed by the бмокщworking mathematician Thus, Chapters 1-3 and 5-6 provide some basics in symplectic geometry, group actions on Kahler manifolds and Borel-Moore homology, geometry of semisimple groups, equivariant algebraic K-theory "from scratch," topology and algebraic geometry of flag varieties and conjugacy classes, respectively The material covered by Chapters 5 and 6 (as well as most of Chapter 3) has never been presented in book form Chapters 3-4 and 7-8 form the heart of the book, бсрхаpresenting a uniform approach to representation theory of three quite different objects: (1) Weyl groups; (2) Lie algebra sln; (3) Iwahori-Hecke algebra The results of Chapters 4 and 8 are new, with complete proofs, not to be found elsewhere in the literature The techniques developed are quite general and can be successfully applied to such other areas of mathematics, as Quantum groups, affine Lie algebras, and quantum field theory The exposition is practically self-contained and each chapter potentially serving as a basis for a graduate course 1 edition Авторы Neil Chriss Victor Ginzburg.
