Higher genus Gromov-Witten potential

Usually the distinction between classical and quantum is restricted to the genus 0 part: it distinguishes between degree 0 and any degree GW invariants. In particular degree 0, 3-point invariants just …

What is the kernel of $i^*:H^*(\overline{\mathcal{M}}_{g,n},\mathbb{Q}) \to H^*(\overline{\m...

Let $\overline{\mathcal{M}}_{g,n}$ be the Deligne-Mumford moduli space of stable algebraic curves. I would like to know which rational cohomology classes or at least which tautological classes on $\ov …

Gromov-Witten invariant $\langle p, p, \ell\rangle_{0, 1}$ counting degree $1$, genus $0$ cu...

As Dan says, you can use the divisor equation: $$\langle e_{\alpha_1}, \ldots, e_{\alpha_n}, \ell \rangle_{g,d} = d\ \langle e_{\alpha_1}, \ldots, e_{\alpha_n} \rangle_{g,d} $$ where the $e_{\alpha_ …
