Let $\lambda_g$ denote the top Hodge class on $\overline{\mathcal{M}}_{g,n}$, and let $R_0^*(\overline{\mathcal{M}}_{g,n})$ denote the degree-zero part of its tautological ring. Bu…

Hodge formula conjecture. For $n=0$ or $n=1$, the top polynomial is

Let $A$ be an abelian variety over an algebraic closure of $\mathbb{Q}$ with good reduction to an abelian variety $A_{0}$ over an algebraic closure of a finite field. A Hodge class…
