Joint Harvard-CUHK-YMSC Differential Geometry Seminar: Gopakumar-Vafa type invariants of holomorphic symplectic 4-folds

SEMINARS

April 5, 2022 9:30 pm

Speaker: Dr. Yalong Cao - RIKEN Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS), Japan

Gromov-Witten invariants of holomorphic symplectic 4-folds vanish and one can consider the corresponding reduced theory. In this talk, we will explain a definition of Gopakumar-Vafa type invariants for such a reduced...

Math Picture Language Seminar: Analytic Langlands correspondence for complex curves

MATHEMATICAL PICTURE LANGUAGE, SEMINARS

April 5, 2022 9:30 am

Speaker: Edward Frenkel - University of California, Berkeley

I will start the lecture with a brief introduction to various flavors of the Langlands correspondence. I will then explain the setup of a new flavor: the analytic Langlands correspondence...

Regular centralizers and the wonderful compactification

SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY

April 5, 2022 3:00 pm

Speaker: Ana Balibanu - Harvard

The universal centralizer of a complex semisimple adjoint group G is the family of regular centralizers in G, parametrized by the regular conjugacy classes. It has a natural symplectic structure...

SEMINARS, CMSA EVENTS

April 4, 2022 7:00 pm

Speaker: Avi Loeb - Harvard University

Are we alone? It would be arrogant to think that we are, given that a quarter of all stars host a habitable Earth-size planet. Upcoming searches will aim to detect...
