Principles of harmonic analysis by Anton Deitmar( Book )

31 editions published between 2008 and 2014 in English and Undetermined and held by 180 WorldCat member libraries worldwide

This title contains material unavailable elsewhere including the full proof of Pontryagin Duality and the Plancherel Theorem. The authors emphasize Banach algebras as the cleanest way to get many fundamentals results in harmonic analysis
C*-algebras : proceedings of the SFB-Workshop on C*-Algebras, Münster, Germany, March 8-12, 1999 by Joachim J. R Cuntz( Book )

11 editions published in 2000 in English and German and held by 155 WorldCat member libraries worldwide

This book represents the refereed proceedings of the SFB-Workshop on C*-Algebras which was held at Münster in March 1999. It contains articles by some of the best researchers on the subject of C*-algebras about recent developments in the field of C*-algebra theory and its connections to harmonic analysis and noncommutative geometry. Among the contributions there are several excellent surveys and overviews and some original articles covering areas like the classification of C*-algebras, K-theory, exact C*-algebras and exact groups, Cuntz-Krieger-Pimsner algebras, group C*-algebras, the Baum-Connes conjecture and others
Basic bundle theory and K-cohomology invariants by Dale Husemöller( Book )

10 editions published in 2008 in English and held by 43 WorldCat member libraries worldwide

Based on several recent courses given to mathematical physics students, this volume is an introduction to bundle theory with the aim to provide newcomers to the field with solid foundations in topological K-theory. A fundamental theme, emphasized in the book, centers around the gluing of local bundle data related to bundles into a global object. One renewed motivation for studying this subject, which has developed for almost 50 years in many directions, comes from quantum field theory, especially string theory, where topological invariants play an important role
K-theory for group C*-algebras and semigroup C*-algebras by Joachim J. R Cuntz( Book )

9 editions published in 2017 in English and German and held by 28 WorldCat member libraries worldwide

This book gives an account of the necessary background for group algebras and crossed products for actions of a group or a semigroup on a space and reports on some very recently developed techniques with applications to particular examples. Much of the material is available here for the first time in book form. The topics discussed are among the most classical and intensely studied C*-algebras. They are important for applications in fields as diverse as the theory of unitary group representations, index theory, the topology of manifolds or ergodic theory of group actions

Monoidal equivalence of locally compact quantum groups and application to bivariant K-theory by Jonathan Crespo( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

This dissertation deals with the notion of monoidal equivalence of locally compact quantum groups and its applications. We generalize to the case of regular locally compact quantum groups, two important resultst concerning the actions of compact quantum groups. Let G1 and G2 be two regular locally compact quantum groups monoidally equivalent. We develop an induction procedure and we build an equivalence of the categories, whose objects are the continuous actions of G1 and G2 on C*-algebras. As an application of this result, we obtain a canonical equivalence of the categories of equivariant KK-theory for actions of G1 and G2. We introduce and investigate a notion of actions on C*-algebras of mesured quantum groupoids on a finite basis. The proof of the second equivalence relies on a version of the Takesaki-Takai duality theorem for continuous actions of measured quantum groupoids on a finite basis. We conclude by defining and studying a notion of equivariant Hilbert modules for actions of mesured quantum groupoids on a finite basis
