Moduli spaces and formal operads
Let M̲g,l be the moduli space of stable algebraic curves of genus g with l marked points. With the operations that relate the different moduli spaces identifying marked points, the family (M̲g,l)g,l is a modular operad of projective smooth Deligne-Mumford stacks M̲. In this paper, we prove that the modular …
