*Representation Theory and Higher Algebraic K-Theory*, by Aderemi Kuku

Aderemi Kuku's monograph

*Representation Theory and Higher Algebraic K-Theory*was published by Chapman & Hall in their Pure and Applied mathematics Series in 2007. The following information is taken from the publisher's leaflet advertising the book.**The definitive resource for algebraic**

*K*-theory'Representation Theory and Higher Algebraic K-Theory' is the first book to present higher algebraic K-theory of orders and group rings as well as characterize higher algebraic K-theory as Mackey functors that lead to equivariant higher algebraic K-theory and their relative generalizations. Thus, this book makes computations of higher K-theory of group rings more accessible and provides novel techniques for the computations of higher K-theory of finite and some infinite groups.

Authored by a premier authority in the field, the book begins with a careful review of classical K-theory, including clear definitions, examples, and important classical results. Emphasizing the practical value of the usually abstract topological constructions, the author systematically discusses higher algebraic K-theory of exact, symmetric monoidal, and Waldhausen categories with applications to orders and group rings and proves numerous results. He also defines profinite higher K- and G-theory of exact categories, orders, and group rings. Providing new insights into classical results and opening avenues for further applications, the book then uses representation-theoretic techniques - especially induction theory - to examine equivariant higher algebraic K-theory, their relative generalizations, and equivariant homology theories for discrete group actions. The final chapter unifies Farrell and Baum-Connes isomorphism conjectures through Davis-Lück assembly maps.

**Features**

- Presents higher algebraic K-theory of orders and group rings for the first time in book form

- Explores connections between C_G and higher algebraic K-theory of C_G for suitable categories, such as exact, symmetric monoidal, and Waldhausen

- Collects methods that have been known to work for computations of higher K-theory of noncommutative rings, such as orders and group rings

- Describes all higher algebraic K-theory as Mackey functors that lead to equivariant higher algebraic K-theory and their relative generalizations for finite, profinite, and compact Lie group actions

- Obtains results on higher K-theory of orders lambda, and hence group rings, for all n ≥ 0

- Uses computations of higher K-theory of orders that automatically yield results on higher K-theory of RG(G finite) to produce results on higher K-theory of some infinite groups

- Provides appendices with many known computations and open problems in classical and higher algebraic K-theory of orders, group rings, and related structures
