Abstract:
How do you count curves in a smooth variety? One approach is to study Gromov-Witten theory. Gromov-Witten invariants give a virtual count of the number of curves on a smooth projective variety with given conditions. 

In this talk, I will introduce the moduli space of stable maps and the Gromov-Witten invariants. Then I will sketch a genus zero computation on P^2.
