    The Goldman bracket characterizes homeomorphisms between non-compact surfaces
    Sumanta Das (IIT Bombay)

    We show that a homotopy equivalence between two non-compact orientable surfaces is homotopic to a homeomorphism if and only if it preserves the Goldman bracket, provided our surfaces are neither the plane nor the punctured plane.

    Venue: LHC, IISER Kolkata
