Pólya enumeration, wreath product symmetric functions, and moduli spaces of curves

Siddarth Kannan, Terry Dekun Song

We develop a calculus for $S_{n}$ -equivariant Euler characteristics of moduli spaces of stable curves and stable maps. Our approach involves an enrichment of Pólya's cycle index poly…

Automorphisms of tropical Hassett spaces

Sam Freedman, Joseph Hlavinka, Josephine Hlavinka +1

Given an integer $g \geq 0$ and a weight vector $w \in Q^{n} \cap (0, 1]^{n}$ satisfying $2 g - 2 + \sum w_{i} > 0$ , let $Δ_{g, w}$ denote the moduli space of $n$ -marked, $w$ -sta…

Topology of tropical moduli spaces of weighted stable curves in higher genus

Siddarth Kannan, Shiyue Li, Stefano Serpente +1

Given integers $g \geq 0$ , $n \geq 1$ , and a vector $w \in (Q \cap (0, 1])^{n}$ such that $2 g - 2 + \sum w_{i} > 0$ , we study the topology of the moduli space $Δ_{g, w}$ of…

Symmetries of tropical moduli spaces of curves

Siddarth Kannan

We compute the automorphism group $Aut (Δ_{g, n})$ for all $g, n \geq 0$ such that $3 g - 3 + n > 0$ , where $Δ_{g, n} \subset M_{g, n}^{trop}$ is the moduli space of…
