Comparing the slice and ribbon genera of knots via braided surfaces
by
Mark Hughes
Stony Brook University

In this talk I will discuss bounds on the slice genus of a knot coming from it's representation as a braid closure, starting with the slice-Bennequin inequality. From there I will use surface braiding techniques of Rudolph and Kamada to exhibit a new lower bound on the ribbon genus of a knot, given some knowledge about what slice surfaces it bounds.
