The p-adic Borel Hyperbolicity of A_g

IASM Distinguished Lectures：The p-adic Borel Hyperbolicity of A_gTime: July 27 Thursday, 16:15-17:15 Venue: 东7报告厅Speaker: 朱歆文 Xinwen Zhu (Stanford University) Abstract. A theorem of Borel says that any holomorphic map from a smooth complex algebraic variety to a smooth arithmetic variety is automatically an algebraic map. The key ingredient is to show that any holomor...

Hölder stability of quantitative photoacoustic tomography based on partial data

题目： Hölder stability of quantitative photoacoustic tomography based on partial data.报告时间:2023年7月26日 10：00-11：00报告地点：海纳苑2幢210报告厅摘要: The talk is related to the inverse problem of reconstructing the diffusion and absorption coefficients of the diffusion equation from internal data in photo-acoustic imaging. I will show that the problem is Hölder stable in subregi...

Stable nearly self-similar blowup of the 2D Boussinesq and 3D Euler equations with smooth data

Title: Stable nearly self-similar blowup of the 2D Boussinesq and 3D Euler equations with smooth data 报告人：陈嘉杰 (Courant Institute, New York University)时间：7月14日(周五)，15:00-16:00，海纳苑2幢204室Abstract: Whether the 3D incompressible Euler equations can develop a finite-time singularity from smooth initial data is an outstanding open problem. In this talk, we will first...
