Height moduli of elliptic surfaces: Motivic height zeta rationality and Kudla-Millson modularity of Mordell-Weil rank jumps

Jun-Yong Park

Let $k$ be a perfect field with $char (k) \neq = 2, 3$ , set $K = k (t)$ , and let $W_{n}^{m i n}$ be the moduli stack of minimal elliptic curves over $K$ of Faltings height…

Motive of the moduli stack of rational curves on a weighted projective stack

Jun-Yong Park, Hunter Spink

We show the compactly supported motive of the moduli stack of degree $n$ rational curves on the weighted projective stack $P (a, b)$ is of mixed Tate type over any base fie…
