Title: The R-matrix from the Virasoro algebra.

Speaker: Noah Arbesfeld.

Time: Nov 1.

Abstract: In his lectures, Vanya explained how to construct a geometric R-matrix using stable envelopes. I'll give another construction in the special case of instanton moduli space that uses the action of a certain Virasoro algebra on the cohomology of the Hilbert scheme of points on C^2 and explain why this construction coincides with the one we've already seen. .
