Seminar November 1 – Chris Atkinson

On November 1st, Chris Atkinson of Temple University will speak in the the Geometry-Topology Seminar.  He will speak about:

Title: Small volume link orbifolds

Abstract: We will discuss recent joint work with Dave Futer in which we study hyperbolic 3-orbifolds having singular locus a link. We have identified the smallest volume hyperbolic 3-orbifold having base space the 3-sphere and singular locus a knot. We also identify the smallest volume hyperbolic 3-orbifold with base space any homology 3-sphere and singular locus a link. With weaker homology assumptions, we obtain a lower bound on the volume of any link orbifold.
