Random branched covers of 2-complexes

Jean-Francois Lafont ⟨lafont.1@osu.edu⟩

I’ll introduce a random model for branched covers of 2-complexes. I’ll explain why asymptotically almost surely, a random branched cover has Gromov hyperbolic fundamental group. This is joint work with Hyeran Cho (OSU) and Rachel Skipper (Univ. Utah).
