Dual boundary complexes of Betti moduli spaces


Abstract: The homotopy type conjecture is part of the geometric P=W conjecture in non-abelian Hodge theory over curves. It states that (the dual boundary complex of) the smooth Betti moduli space of complex dimension d is homotopy equivalent to a sphere of dimension d-1. In this talk, via a microlocal/contact geometric perspective, I will explain a proof of the conjecture for a class of rank n wild character varieties over the two sphere with one puncture, associated to any Stokes Legendrian knot defined by a n-strand positive braid.
