报告人简介: 著名国际数学大师Haim Brezis教授现为美国Rutgers 大学数学教授,同时也是以色列理工大学(Technion)教授。他是非线性泛函分析和偏微分方程方面的主要领导者之一,是法国科学院院士、欧洲科学院院士、美国科学院等外籍院士。Brezis教授还是位教育大师,他撰写的《泛函分析》教材是传世之经典,至今指导58位博士生,其中1位(P.L.Lions(1994))获得数学界最高荣誉Fields奖,另有2位学术后裔获Fields奖(C.Villani(2010), A.Figalli(2018)。 报告内容: I will discuss two proofs of the celebrated Monge-Kantorovich theorem in discrete Optimal Transport (OT). One of them is extremely elementary, self-contained, and can be understood by beginners. I will then describe an application to Liquid Crystals, which provides an explicit formula for the least energy required to produce a configuration with assigned defects. Next I will present striking connections that we recently discovered with P. Mironescu between OT and least area formulas for the classical Plateau problem. |
