The Quillen and sharbly Hopf algebra structures on Steinberg homology coincide
Urshita Pal, Sam Payne
Two recent constructions independently give bigraded commutative Hopf algebra structures on the homology of with rational Steinberg coefficients. One, by…
Extensions of tautological rings and motivic structures in the cohomology of
Samir Canning, Hannah Larson, Sam Payne
We study collections of subrings of that are closed under the tautological operations that map cohomology classes on moduli spaces of smaller di…
Adic tropicalizations and cofinality of Gubler models
Tyler Foster, Sam Payne
We introduce adic tropicalizations for subschemes of toric varieties as limits of Gubler models associated to polyhedral covers of the ordinary tropicalization. Our main result sho…
Avoidance loci and tropicalizations of real bitangents to plane quartics
Hannah Markwig, Sam Payne, Kris Shaw
We compare two partitions of real bitangents to smooth plane quartics into sets of 4: one coming from the closures of connected components of the avoidance locus and another coming…
Weight 11 compactly supported cohomology of moduli spaces of curves
Sam Payne, Thomas Willwacher
We study the weight 11 part of the compactly supported cohomology of the moduli space of curves , using graph complex techniques, with particular attention to the case $n…
-rings of wonderful varieties and matroids
Matt Larson, Shiyue Li, Sam Payne +1
We study the -ring of the wonderful variety of a hyperplane arrangement and give a combinatorial presentation that depends only on the underlying matroid. We use this combinator…
