Enumerative geometry of higher genus curves on quintic threefolds -- Felix Janda, February 7, 2020

Quintic threefolds are one of the simplest classes of Calabi-Yau threefolds, and have been studied from many perspectives. In particular, they have been a rich source of enumerative problems, starting from Schubert's count of lines on a generic quintic threefold, and with renewed interest after surprising predictions of string theorists. In my talk, I will introduce a new approach (joint with Q. Chen, S. Guo and Y. Ruan) toward computing Gromov-Witten counts of higher genus curves on quintic threefolds (and more general complete intersections).
