Abstract

In this paper we continue the work of using the recent advances in algebraic KK-theory to extend computations done in characteristic pp to the mixed characteristic setting using perfectoid rings. We extend the work of Hesselholt-Nikolaus in \cite{Hesselholt_Nikolaus} on the algebraic KK-Theory of cuspidal curves. We consider both cuspidal curves and the pp-completion of cuspidal curves. Along the way we also study the KK-theory of the pp-completed affine line over a perfectoid ring.
