Cohomology of mapping class groups and the abelian moduli space

Jørgen Ellegaard Andersen, Rasmus Villemoes

We consider a surface Σ of genus g≥3, either closed or with exactly one puncture. The mapping class group Γ of Σ acts symplectically on the abelian moduli space $M = \…

On Reducibility of Mapping Class Group Representations: The SU(N) Case

Jørgen Ellegaard Andersen, Jens Fjelstad

We review and extend the results of [1] that gives a condition for reducibility of quantum representations of mapping class groups constructed from Reshetikhin-Turaev type topologi…
