Link homology, bridge trisections, and invariants of knotted surfaces
by
Adam Saltz
University of Georgia

I will describe an invariant of knotted surfaces in S^4 obtained by applying link homology to Meier and Zupan's bridge trisections. This invariant takes values in Z/2Z and distinguishes the unknotted sphere from the spun (2,3)-torus knot. I'll finish with some more speculative connections to transverse links and links in other three-manifolds.
