Location:  3866 East Hall (5:00 PM to 6:00 PM)

Title:  FSop modules and the homology of Deligne-Mumford compactifications

Abstract:   The space \bar M_{g,n} is a compactification of the moduli space algebraic curves with marked points, obtained by allowing smooth curves to degenerate to nodal ones. We will talk about how the structure of its homology, H_i(\bar M_{g,n}), for n >> 0 is governed by an action of the category of finite sets and surjections.
