Algebraic Geometry 2025-07-15 v1

Abstract

We study the weight-graded compactly supported cohomology of the moduli spaces of curves Mg,n\mathcal{M}_{g,n} using the Getzler-Kapranov graph complex. After recollecting the theory and some previous results, we compute the cohomology in weight 13 for the (g, n) pairs with 3g + 2n = 28.
