A new cohomology class on the moduli space of curves

Paul Norbury

We define a collection $Θ_{g, n} \in H^{4 g - 4 + 2 n} (M_{g, n}, Q)$ for $2 g - 2 + n > 0$ of cohomology classes that restrict naturally to boundary divisors. We prove that…

Topological recursion with hard edges

Leonid Chekhov, Paul Norbury

We prove a Givental type decomposition for partition functions that arise out of topological recursion applied to spectral curves. Copies of the Konstevich-Witten KdV tau function…
