What is… Gromov-Written theory?

The most basic question in enumerative Geometry is: How many lines are there through two distinct points? A natural extension of this question is to count the number Nd of rational curves of degree d passing through 3d-1 points in general position in the complex projective plane. I will explain how to formulate this problem using Gromov-Witten theory and Kontsevich solution to the problem in terms of a recursive formula which reduces the question to the computation of N1 = 1.
