Differential Geometry seminar——Lelong Numbers of $m$-Subharmonic Functions Along Submanifolds


Venue:Zoom Meeting ID:4552601552 Passcode: YMSC

Organizer:Xiaokui Yang, Yingying Zhang

Speaker:Nicholas McCleerey (University of Michigan)


We study the possible singularities of an $m$-subharmonic function $\varphi$ along a complex submanifold $V$ of a compact K\"ahler manifold, finding a maximal rate of growth for $\varphi$ which depends only on $m$ and $k$, the codimension of $V$. When $k < m$, we show that $\varphi$ has at worst log poles along $V$, and that the strength of these poles is moveover constant along $V$. This can be thought of as an analogue of Siu's theorem. This is joint work with Jianchun Chu.

      Entropy, Sobolev Inequaity and Ricci Flow | BIMSA-BIT Differential Geometry Seminar

      AbstractFirst, the concept of entropy in physics and geometry wil be discussed. In particular, Perelman’s W-entropy will bereviewed. Then the relation between entropy and Sobolev inequality and the uniform Sobolev inequality along the Ricci flow due to Rugang Ye will be presented. Some geometric applications such as in the case of Gromov almost flat manifolds will also be presented

      Semifinite harmonic functions on Bratteli diagrams

      AbstractLocally semisimple algebras (LS-algebras) are inductive limits of semisimple algebras, and can be fully characterized by their Bratteli diagrams ($\mathbb{N}$-graded graphs). (Finite) harmonic functions on Bratteli diagrams are a standard tool in the representation theory of LS-algebras and semifinite harmonic functions are a natural generalization. We plan to give an overview of the su...
