-leaky double Hurwitz descendants
Renzo Cavalieri, Hannah Markwig, Johannes Schmitt
We define a new class of enumerative invariants called -leaky double Hurwitz descendants, generalizing both descendant integrals of double ramification cycles and the -leaky…
Étale cohomological stability of the moduli space of stable elliptic surfaces
Oishee Banerjee, Jun-Yong Park, Johannes Schmitt
We compute the (stable) étale cohomology of , the moduli stack of degree morphisms from a smooth projective curve to the weighted p…
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…
Detecting and Counting Small Subgraphs, and Evaluating a Parameterized Tutte Polynomial: Lower Bounds via Toroidal Grids and Cayley Graph Expanders
Marc Roth, Johannes Schmitt, Philip Wellnitz
Given a graph property , we consider the problem , where the input is a pair of a graph and a positive integer , and the task is to decide whether $G…
Counting Induced Subgraphs: An Algebraic Approach to #W[1]-hardness
Julian Dörfler, Marc Roth, Johannes Schmitt +1
We study the problem #IndSub(P) of counting all induced subgraphs of size k in a graph G that satisfy the property P. This problem was introduced by Jerrum and Meeks and shown to b…
