## Colloquium: Tuesday, December 8, 2pm. Speaker: Andrei Minchenko (Weizmann). Title: Linear differential algebraic groups and central extensions.

At the most basic level, a linear differential algebraic group (LDAG) is a group of matrices whose entries are functions satisfying a fixed set of polynomial differential equations. These groups are important for applications to differential Galois theory. Although LDAGs…
