Lie Groups: (v.225 Graduate Texts in Mathematics)

This book is intended for a one year graduate course on Lie groups and Lie algebras. The author proceeds beyond the representation theory of compact Lie groups (which is the basis of many texts) and provides a carefully chosen range of material to give the student the bigger picture. For compact Lie groups, the Peter-Weyl theorem, conjugacy of maximal tori (two proofs), Weyl character formula and more are covered. The book continues with the study of complex analytic groups, then general noncompact Lie groups, including the Coxeter presentation of the Weyl group, the Iwasawa and Bruhat decompositions, Cartan decomposition, symmetric spaces, Cayley transforms, relative root systems, Satake diagrams, extended Dynkin diagrams and a survey of the ways Lie groups may be embedded in one another. The book culminates in a "topics" section giving depth to the student's understanding of representation theory, taking the Frobenius-Schur duality between the representation theory of the symmetric group and the unitary groups as a unifying theme, with many applications in diverse areas such as random matrix theory, minors of Toeplitz matrices, symmetric algebra decompositions, Gelfand pairs, Hecke algebras, representations of finite general linear groups and the cohomology of Grassmannians and flag varieties.Daniel Bump is Professor of Mathematics at Stanford University. His research is in automorphic forms, representation theory and number theory. He is a co-author of GNU Go, a computer program that plays the game of Go. His previous books include Automorphic Forms and Representations (Cambridge University Press 1997) and Algebraic Geometry (World Scientific 1998).

Review :
From the reviews: "This book is a nice and rich introduction to the beautiful theory of Lie groups and its connection to many other areas of mathematics." (Karl-Hermann Neeb, Mathematical Reviews, 2005f) "As Lie theory prerequisites can pose a great hurdle to number-theory students attracted to this program, Bump's book will find an enthusiastic clientele even in an already crowded market. It will particularly delight readers who already know some of this material: the many short chapters generally begin with a map of the precise regress necessary to start wherever one ought. Summing Up: Highly recommended." (D.V. Feldman, CHOICE, Vol. 42 (8), April, 2005) "This book is intended for a one-year graduate course on Lie groups and Lie algebras. The author proceeds beyond the representation theory of compact Lie groups ... and provides a carefully chosen range of material to give the student the bigger picture." (L'Enseignement Mathematique, Vol. 50 (3-4), 2004) "This book aims to be a course in Lie groups that can be covered in one year with a group of seasoned graduate students. ... offers a wealth of complementary, partly quite recent material that is not found in any other textbook on Lie groups. ... this book covers an unusually wide spectrum of topics ... . the entire presentation is utmost thorough, comprehensive, lucid and absolutely user-friendly. ... All together, this graduate text his a highly interesting, valuable and welcome addition ... . (Werner Kleinert, Zentralblatt MATH, Vol. 1053, 2005) "Reductive Lie groups and their representations form a very broad field. The aim of the book is to select essential topics for a year course for graduate students ... . The book is nicely written and efficiently organized. ... The presented book brings a beautiful selection of a number of further important additional topics, which are worth to include into a course. It is a very important addition to existing literature on the subject." (EMS Newsletter, June, 2005) "This book gives an introduction on the graduate level to the subject of Lie groups, Lie algebras and their representation theory. The presentation is well organized and clear ... . this book is a very interesting and valuable addition to the list of already existing books on Lie groups." (J. Mahnkopf, Monatshefte fur Mathematik, Vol. 147 (3), 2006)
