5:00PM: A Riemann-Hurwitz-Plucker Formula
Adrian Zahariuc
The classical Riemann-Hurwitz and Plucker formulas count the number of ramification points of maps from projective curves into other curves and projective spaces respectively, and overlap in the case of maps to the projective line. In this talk, after reviewing these two formulas, I will state a common generalization which applies to maps from curves into arbitrary projective varieties, with ramification defined relative to an arbitrary flat family of divisors on the target. (This is joint work with Brian Osserman.)
