Geometry and Physics Seminar (GPS)

Speaker: Yalong Cao (MCM)Time: June 16, 2026, 10:00-11:30Place: 新水利馆 300, Tsinghua UniversityTitle: Quivers with potentials and their Yangian symmetryAbstract: Symmetric quivers with potentials are geometric objects that provide generalizations of Nakajima quiver varieties. There are naturally defined Yangian type quantum group actions on their critical cohomologies. The associated Lie (sup...

YMSC Topology Seminar

Title: Bombieri type inequalities and equidistribution of points on surfaces Speaker: Håkan HEDENMALM (KTH)Abstract:This talk is concerned with packing a given number of points in a good way on a compact Riemann surface. In the case of the Riemann sphere the packing is related with the iterated Bombieri inequality. Close to optimal bounds for the sphere were found by Beltran and Etayo for expo...
