Hodge theory of the Goldman bracket

### Richard Hain

Geometry & Topology 24 (2020) 1841–1906
##### Abstract

We show that, after completing in the $I$–adic topology, the Goldman bracket on the space spanned by the closed geodesics on a smooth, complex algebraic curve $X$ is a morphism of mixed Hodge structures. We prove similar statements for the natural action of the loops in $X$ on paths from one boundary vector to another.

 Dedicated to the memory of Stefan Papadima
