Twisted K-Theory and Finite-Dimensional Approximation

Read/Search this Article

Abstract

We provide a finite-dimensional model of the twisted K-group twisted by any degree three integral cohomology class of a CW complex. One key to the model is Furuta’s generalized vector bundle, and the other is a finite-dimensional approximation of Fredholm operators.
