Let $g,n$ be such that the moduli space $\overline{\mathcal{M}}_{g,n}$ of stable curves is defined, and let $\mathbf{e}=(e_1,\ldots,e_n)$ be a vector of nonnegative integers satisf…

For nonnegative integers $g,n,d1, oops$ satisfying $2g-2+n0$ and $d1+cdots+dn=3g-3+n$, let $mathcal{G}{d1,dots,dn}(g)$ denote the normalized psi-class intersection numbers. For fix…
