Abstract

We use descent theoretic methods to solve the homotopy limit problem for Hermitian $K$-theory over quasicompact and quasiseparated base schemes. As another application of these descent theoretic methods, we compute the cellular Picard group of 2-complete Hermitian $K$-theory over $\text{ Spec}\left(ℂ\right)$, showing that the only invertible cellular spectra are suspensions of the tensor unit.
