Hermitian K-theory for stable infinity categories with duality

Algebro-Geometric and Homotopical Methods

28 February 15:00 - 16:00

Markus Spitzweck - University of Osnabrück

We will carry over the hermitian Waldhausen construction to stable infinity categories with duality obtaining a connective hermitian K-theory spectrum, which is in fact part of a genuine C_2-spectrum, the real K-theory spectrum. If the construction is applied to perfect complexes over a commutative ring in which 2 is invertible we show that we recover classical hermitian K-theory. In the end we might comment on constructions of hermitian K-theory for more general classes of infinity categories with duality.
