Curves in Pn: inductive enumeration by dimension

Grigory Mikhalkin

University of Toronto


Abstract

The enumerative problem we are concerned about is computing the number of curves of given degree and genus subject to some incidence conditions in Pn (over complex or real numbers). We present an inductive (by n) solution that reduces such problems to the corresponding enumerative problem in P1 (which is trivial). Joint work with E. Brugalle.
