DESCRIPTION:Craig Westerland\, University of Minnesota\n\nAbstract: Hurwitz
moduli spaces parameterize branched covers of algebraic curves. In this t
alk\, I’ll focus on branched covers of the affine line and explain several
approaches to understanding the cohomology of these moduli spaces using con
nections to braided Hopf algebras and a new family of braided operads. In
particular\, I hope to convey how an operad which governs multiplicative op
erations on Hurwitz spaces also controls primitives in braided Hopf algebra
s. Time permitting\, I’ll also discuss what little can be said about the a
ction of the absolute Galois group on these cohomology rings.
