From optimal transport to liquid crystals
Haim Brezis - Rutgers University and Technion
Location: Hill 705
Date & time: Thursday, 31 January 2019 at 12:00PM - 1:00PM
Abstract: The purpose of this talk is two-fold:
1) I will present an extremely simple self-contained proof of the celebrated Monge-Kantorovich theorem for the discrete case of Optimal Transport. It can be taught in less than one hour to first-year math students.
2) I will discuss an application taken from my 1986 paper with Coron and Lieb on Liquid Crystals, which provides an explicit formula for the least energy required to produce a configuration with assigned topological defects.
If time permits I will mention ongoing developments, joint with P. Mironescu and I. Shafrir, concerning the least energy required to pass from a given configuration to another one.
