Integrals of -classes on twisted double ramification cycles and spaces of differentials
Matteo Costantini, Adrien Sauvaget, Johannes Schmitt
We prove a closed formula for the integral of a power of a single -class on strata of -differentials. In many cases, these integrals correspond to intersection numbers on twi…
Chow rings of stacks of prestable curves II
Younghan Bae, Johannes Schmitt
We continue the study of the Chow ring of the moduli stack of prestable curves begun in [arXiv:2012.09887v2]. In genus , we show that the Chow ring of $\mat…
Parameterized (Modular) Counting and Cayley Graph Expanders
Norbert Peyerimhoff, Marc Roth, Johannes Schmitt +2
We study the problem of counting -edge subgraphs satisfying a given graph property in a large host graph . Building upon the breakthrough result o…
The Hodge bundle, the universal 0-section, and the log Chow ring of the moduli space of curves
Samouil Molcho, Rahul Pandharipande, Johannes Schmitt
We bound from below the complexity of the top Chern class of the Hodge bundle in the Chow ring of the moduli space of curves: no formulas in terms of classes of degrees 1 and 2 can…
