Topological K-theory is one of the most important invariants for
noncommutative algebras. Bott periodicity, homotopy invariance, and
various long exact sequences distinguish it from algebraic K-theory.
This book describes a bivariant K-theory for bornological algebras,
which provides a vast generalization of topological K-theory. In
addition, it details other approaches to bivariant K-theories for
operator algebras. The book studies a number of applications, including
K-theory of crossed products, the Baum-Connes assembly map, twisted
K-theory with some of its applications, and some variants of the
Atiyah-Singer Index Theorem.
