Hsian-Hua Tseng (OSU)Abstract
Hurwitz numbers are certain combinatorial quantities that admit several different-looking definitions. One way to define Hurwitz numbers is to say that the are counts of covers of the Riemann sphere with specific ramifications. Hurwitz numbers are related to various different areas of mathematics, such as moduli theory and integrable systems. In this talk I will attempt to discuss some of the definitions of Hurwitz numbers, and outline the connections to other areas.
