Chu spaces generalize the notion of topological space by dropping the requirements that the set of open sets be closed under union and finite intersection, that the open sets be extensional, and that the membership predicate (of points in open sets) be two-valued. The definition of continuous function remains unchanged other than having to be worded carefully to continue to make sense after these generalizations. The name is due to Po-Hsiang Chu, who originally constructed a verification of autonomous categories as a graduate student under the direction of Michael Barr in 1979. (Wikipedia).

Abstract: We show that surfaces arising as canonical covers of Enriques and bielliptic surfaces do not have any non-trivial FourierMukai partner, extending result of Sosna for complex surfaces. This is a joint work with K. Honigs and L. Lombardi. Recording during the thematic meeting: "H
