This GEMS session will be facilitated by Professor Jemma Lorenat from Pitzer College. Title: Playing with the Rules of Geometries Abstract: This session will explore how a small set of rules can be used […] |
1 event,We’ll first define the two-point gravitational correlators which appeared last week as descendant Gromov-Witten invariants. By request, we’ll then introduce Gromov-Witten invariants as they appear in the expository work https://arxiv.org/abs/2501.03232 and give CP^1 to demonstrate some of the identities which GW invariants satisfy. If time allows, we’ll also give the small and big quantum cohomology for CP^1. |

Speaker: Scott Taylor, Professor of Mathematics, Colby College, Maine Title: Sums and Symmetries Abstract: Adding is one of the fundamental mathematical operations and we like it so much, we can't help but add all kinds of things including knots, surfaces, and 3-dimensional spaces. Symmetry is also a fundamental mathematical concern. How well do sums and […] |
