Computing top intersections in the tautological ring of $M_g$

Algebraic Geometry 2013-03-28 v1

Abstract

We derive effective recursion formulae of top intersections in the tautological ring R(Mg)R^*(M_g) of the moduli space of curves of genus g2g\geq 2. As an application, we prove a convolution-type tautological relation in Rg2(Mg)R^{g-2}(M_g).
