Multifunctorial inverse $K\mkern-2mu$-theory

Niles Johnson and Donald Yau
Vol. 7 (2022), No. 3, 507–548
DOI: 10.2140/akt.2022.7.507
Abstract

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