Schur-type invariants of branched G-covers of surfaces

Eric Samperton

Fix a finite group $G$ and a conjugacy invariant subset $C \subseteq G$ . Let $Σ$ be an oriented surface, possibly with punctures. We consider the question of when two homomorphisms…

Computational complexity and 3-manifolds and zombies

Greg Kuperberg, Eric Samperton

We show the problem of counting homomorphisms from the fundamental group of a homology $3$ -sphere $M$ to a finite, non-abelian simple group $G$ is #P-complete, in the case that $G$ …
