One early success of the theory was Kontsevich\u2019s recursive formula for enumerating the number of rational plane curves through 3d-1 points in general position. Starting from a consideration of which genus 0 Gromov-Witten invariants for the complex projective plane can possibly be non-zero, we will assemble a generating function for these invariants, called the genus 0 Gromov-Witten potential for the complex projective plane. If time allows, we will also use the fact that the potential satisfies a partial differential equation called the Witten-Dijkgraaf-Verlinde-Verlinde equation to solve for N_d, the coefficients of the generating function, which give the number of rational plane curves through 3d-1 points.<\/p>\n<p>This talk follows p. 24-26 of these notes, available at https:\/\/arxiv.org\/abs\/2501.03232.<\/p>\n<p>All are welcome.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We especially welcome all undergraduates and graduate students to attend topology seminar!
