Monodromy Representations of Mixed Braid Groups

Geometric Topology 2026-04-02 v1 Representation Theory

Abstract

We explicitly describe unitary representations of mixed braid groups on the cohomology of Abelian branched covers of CP1\mathbf{CP}^1 . We show that the image of the representation is generated by complex reflections and relate it to the multivariate Burau representation.
