The Chow ring of the moduli space of degree $2$ quasi-polarized K3 surfaces

Samir Canning, Dragos Oprea, Rahul Pandharipande

We study the Chow ring with rational coefficients of the moduli space ${\mathcal{F}}_2$ of quasi-polarized $K3$ surfaces of degree $2$. We find generators, relations, and calculate…
