Navier - Stokes equation is one of the most important equations in mathematics with applications to fluid dynamics, etc. It is also one of the most difficult equation to study. Indeed, the regularity (smoothness) problem of the solutions in 3-dimensional space is one of the seven Millennium Mathematical Problems proposed by Clay Institute.

Professor Fanghua Lin, Silver Chair Professor at Courant Institute, is an expert on Navier-Stokes equation and one of the best analysts in the world. He is the 2002 Bocher prizer winner of American Mathematical Society. Among his many other distinctions, he is a member of American Academy of Arts and Sciences, and was a Presidential Young Investigator.

The talk is aimed at general audience.
