Multifunctorial Inverse $K$-Theory

Abstract

We show that Mandell's inverse KK-theory functor is a categorically-enriched non-symmetric multifunctor. In particular, it preserves algebraic structures parametrized by non-symmetric operads. As applications, we describe how ring categories arise as the images of inverse KK-theory.
