A Refined Derived Torelli Theorem for Enriques surfaces, II: the non-generic case (2104.13610v2)
Published 28 Apr 2021 in math.AG and math.CT
Abstract: We prove that two Enriques surfaces defined over an algebraically closed field of characteristic different from $2$ are isomorphic if their Kuznetsov components are equivalent. This improves and completes our previous result joint with Nuer where the same statement is proved for generic Enriques surfaces.
