(Semi)topological $K$-theory via solidification

K-Theory and Homology 2024-09-04 v1 Operator Algebras Rings and Algebras

Abstract

Clausen--Scholze introduced the notion of solid spectrum in their condensed mathematics program. We demonstrate that the solidification of algebraic KK-theory recovers two known constructions: the semitopological KK-theory of a real (associative) algebra and the topological (aka operator) KK-theory of a real Banach algebra.
