某些infinite dimensional空间的扭曲K理论、K-同调和双变Chern-Connes型character

Twisted K-theory, K-homology and bivariant Chern-Connes type character of some infinite dimensional spaces

Snigdhayan Mahanta

摘要:

本文在双变的背景下研究了无穷维空间如SU(\infty)的扭曲K理论和K同调。利用Cuntz的一般方法,我们在可分σ-C^*-代数范畴上构造了一个双变K理论,它推广了(局部)紧空间的扭曲K理论和K同调.构造了一个取值于双变局部循环同调的双变Chern-Connes型特征标.在合理的假设下,分析了从(解析)K-同调到局部循环上同调的对偶Chern-Connes特征标的结构.我们还研究了局部凸代数上的扭周期循环同调和C^*-代数上的局部循环同调(在紧情形下).

英文摘要:

We study the twisted K-theory and K-homology of some infinite dimensional spaces, like SU(\infty), in the bivariant setting. Using a general procedure due to Cuntz we construct a bivariant K-theory on the category of separable σ-C^*-algebras that generalizes both twisted K-theory and K-homology of (locally) compact spaces. We construct a bivariant Chern--Connes type character taking values in bivariant local cyclic homology. We analyse the structure of the dual Chern--Connes character from (analytic) K-homology to local cyclic cohomology under some reasonable hypotheses. We also investigate the twisted periodic cyclic homology via locally convex algebras and the local cyclic homology via C^*-algebras (in the compact case).
