摘要

本文研究了扭曲群胚C*-代数的K理论。证明了满足Baum–Connes猜想的充分群胚上的一个带系数的扭转的同伦论导致了相应扭转群胚C*-代数的K理论群之间的同构。该结果也在逆半群中得到了解释，并应用于广义Renault–Deaconu群胚和P-图代数。

K-theory and homotopies of twists on ample groupoids

This paper investigates the K-theory of twisted groupoid C*-algebras. It is shown that a homotopy of twists on an ample groupoid satisfying the Baum–Connes conjecture with coefficients gives rise to an isomorphism between the K-theory groups of the respective twisted groupoid C*-algebras. The results are also interpreted in an inverse semigroup setting and applied to generalized Renault–Deaconu groupoids and P-graph algebras.
