Title: Small covers of big surfaces.
Abstract: I will talk about work in progress with Alan McLeay investigating the following apparently innocent question: Given two surfaces, when does there admit a finite-sheeted cover of one over the other? A complete answer is available if the two surfaces are of finite type. In the infinite-type world, the question appears to be less innocent than one might expect.
