11:30 Aula Gris 2 ICMAT Speaker: Alan McLeay (ICMAT/CSIC) Title: Small covers of big surfaces Abstract: Covering spaces are ubiquitous in topology. This talk will be about finite-sheeted covers of surfaces. In particular, one can ask; given two surfaces, when does one admit such a cover over the other. A result of Massey provides the answer when the surfaces are finite-type. In joint work with Ty Ghaswala, we look at what can be said about the remaining (uncountably many) cases.
