Denis Nardin (Université Paris 13, France): A universal property for Hermitian K-theory

Abstract

In this talk we construct a category of hermitian noncommutative motives and we prove that the hermitian K-theory functor is corepresentable by the noncommutative motive of the sphere spectrum. The approach taken clarifies the relation between the different definitions of hermitian K-theory and L-theory in the literature when 2 is not invertible.
