Moduli of relative stable maps to $P^{1}$ : cut-and-paste invariants

Siddarth Kannan

We study constructible invariants of the moduli space $M (x)$ of stable maps from genus zero curves to $P^{1}$ , relative to $0$ and $\infty$ …

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…

Chow Rings of Heavy/Light Hassett Spaces via Tropical Geometry

Siddarth Kannan, Dagan Karp, Shiyue Li

We compute the Chow ring of an arbitrary heavy/light Hassett space $M ˉ_{0, w}$ . These spaces are moduli spaces of weighted pointed stable rational curves, where the associated…
