The homotopy limit problem and the cellular Picard group of Hermitian K-theory

Abstract

We use descent theoretic methods to solve the homotopy limit problem for Hermitian K-theory over quasi-compact and quasi-separated base schemes. As another application of these descent theoretic methods, we compute the cellular Picard group of 2-complete Hermitian K-theory over Spec(C), showing that the only invertible cellular spectra are suspensions of the tensor unit.
