Motivic quasimap wall-crossing for Grassmannians

Siddarth Kannan, Terry Dekun Song

We prove a wall-crossing formula for the Euler characteristics, considered as virtual mixed Hodge structures, of moduli spaces of $ε$ -stable quasimaps to the Grassmannian…

Automorphisms of the boundary complex of $M_{0, n} (P^{r}, d)$

Arjun Joisha, Siddarth Kannan

We compute the automorphism group of the dual complex $T_{d, n}$ of the boundary divisor in the Kontsevich moduli space $M_{0, n} (P^{r}, d)$ . W…

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…

Euler characteristics of the universal Picard stack

Siddarth Kannan

We study $S_{n}$ -equivariant weight-graded and topological Euler characteristics of the universal Picard stack $Pic_{g, n}^{d} \to M_{g, n}$ of degree- $d$ l…

Virtual Hodge numbers of $M_{g, n} (P^{r}, d)$ : stability and calculations

Siddarth Kannan, Terry Dekun Song

We study $S_{n}$ -equivariant motivic invariants of the moduli space $M_{g, n} (P^{r}, d)$ of degree- $d$ maps from $n$ -pointed curves of genus $g$ to $\mathbb…
