ICMS-IMSA Working Seminar

August 20, 2021

ICMS, Room 403, 4:30-6:30 pm,
Broadcasted trough Zoom

Title: On determinantal cubic hypersurfaces (after Iliev-Manivel, Beauville,…)

Speaker: Prof. R. Mboro IMSA, ICMS, 4:30-5:30 pm

Abstract: We give an account of the problem of writing an equation of a cubic (or other degree) hypersurface X as a (kind of) determinant of a matrix with homogeneous entries. Expressing the equation of X as a determinant is equivalent to produce an arithmetically Cohen-Macaulay vector bundle on X. The talk will focus on the cases of cubic hypersurfaces of dimension at most 8.

Title: Quantum representations of fundamental groups of curves with infinite image

Speaker: Prof. R. Aguilar IMSA, ICMS, 5:30-6:30 pm

Abstract: We will report on some results due to Koberda-Santharoubane that show that an element of $\pi_1(P^1 – 3 points) has an infinite order under some quantum representations of the mapping class group. Тhe lectures will be held in hall 403 of the Institute of Mathematics and Informatics.

Тhe lectures will be held in hall 403 of the Institute of Mathematics and Informatics and broadcasted through Zoom:
