​BIMSA-YMSC Geometry and Dynamics Seminar

Upcoming Talk:Date and Time: April 16 (Wednesday) at 1:30-2:30pmZoom Meeting ID: 815 762 8413 (Passcode: BIMSA)Speaker: Yinbang Lin (Tongji University)Title: An update on the Riemann-Roch and Brill-Noether problems over surfacesAbstract: We try to bound the dimension of the global sections of semistable sheaves in terms of the rank and the first Chern class. This improves the explicit Le Potier...

Differential Geometry Seminar

Schedule.Date: 15 Apr., 2025Speaker: Eleonora Di Nezza (IMJ-PRG, Sorbonne Université) Title: Almost convexity of the Mabuchi functional in singular settings Abstract: The Mabuchi functional M was introduced by Mabuchi in the 80's in relation to the existence of canonical metrics on a compact Kähler manifold. The critical points of M are indeed constant scalar curvature Kähler (cscK) metrics. Re...
