Equivariant formality in $K$-theory

Algebraic Topology 2019-02-13 v4 K-Theory and Homology

Abstract

In this note we present an analogue of equivariant formality in KK-theory and show that it is equivalent to equivariant formality \emph{\`a la} Goresky-Kottwitz-MacPherson. We also apply this analogue to give alternative proofs of equivariant formality of conjugation action on compact Lie groups, left translation action on generalized flag manifolds, and compact Lie group actions with maximal rank isotropy subgroups.
