The Thom isomorphism in gauge-equivariant K-theory
Victor Nistor, Evgenij Troitsky
In a previous paper we have introduced the gauge-equivariant K-theory group of a bundle endowed with a continuous action of a bundle of compact Lie groups. These groups are the nat…

An index for gauge-invariant operators and the Dixmier-Douady invariant
Victor Nistor, Evgenij Troitsky
Let $\GR \to B$ be a bundle of compact Lie groups acting on a fiber bundle . In this paper we introduce and study gauge-equivariant -theory groups $K_\GR^i(Y)$. These g…
