This Saturday there will be a mini-conference in topology at Pitt.
Robin Knight is giving a talk 1:30-2:30pm, in Thackeray 704.
Title: Categories of topological spaces, and duality
Abstract: Given a suitable language L, one can construct a small category of topological spaces from which one can recover a great
deal of information about the models of L, by generalisations of Stone duality. We discuss some of the applications of this
technique to model theory.
