Title: An approach to computing Gromov-Witten invariants Abstract: In the 1990s, theoretical physics gave rise to a new mathematical challenge: computing certain “virtual counts” of curves on manifolds. These counts, called the Gromov-Witten invariants of the manifold, model particle interactions in string theory. In principle one can determine the small-scale geometry of the universe by … Continue reading “Colloquium: Rachel Webb (University of California, Berkeley)”
