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

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.

Quantum representations of fundamental groups of curves with
infinite image

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 and via Zoom.
