Seminar: Yale Algebraic and Tropical Geometry

Spring 2017

The Yale Algebraic and Tropical Geometry seminar meets biweekly on Thursdays for two talks from 3:00 - 4:00 pm and then again from 4:30 - 5:30 in DL 431. Afterward, we usually go to dinner with the speaker at a local restaurant.

Organizers: Asher Auel, Kalina Mincheva, and Sam Payne.

Attend AGNES at Stony Brook on the weekend of April 21 - 23, 2017.
