Title: Many faces of characters Speaker: Nikita Nekrasov Date: Tuesday, April 29, 2014 Time: 1:00pm-2:00pm Place: Lecture Hall 102, Simons Center [box, type=”download”]Watch the video.[/box] Abstract: In representation theory, a character is a function (distribution) on the group, given roughly by the trace of the group element in the given representation. In physics the character is … Read more
Title: Absolute vs Relative Gromov-Witten Invariants Speaker: Aleksey Zinger Date: Tuesday, April 29, 2014 Time: 11:15am-12:15pm Place: Seminar Room 313, Simons Center [box, type=”download”]Watch the video.[/box] Abstract: One might hope that the absolute and relative GW-invariants with the basic contact vector are the same whenever the symplectic divisor contains no curves. I will explain why this … Read more
