Fudan International Seminar on Analysis, PDEs and Fluid mechanics

The speaker: Dr. Xiao Ren (Fudan University)

Title of the talk:“Leray's plane stationary solutions have the prescribed limit at infinity in the case of small Reynolds numbers”.

Time: Thursday, 13 of May 2021, 16:00 - 17:00.

Abstract. In the celebrated 1933 paper, J. Leray proposed the invading domains method to construct D-solutions for the stationary Navier-Stokes flow around obstacle problem. In two dimensions, whether Leray's D-solution achieves the prescribed limiting velocity at spatial infinity became a major open problem since then. In this paper, we solve this problem at small Reynolds numbers. The proof builds on a novel blow-down argument which rescales the invading domains to the unit disc, and the ideas developed in a recent paper [Korobkov-Pileckas-Russo2020], where the nontriviality of Leray solutions in the general case was proved, and [Korobkov-Ren-2021], where the uniqueness result for small Reynolds number was established. The talk is based on a joint work with M.Korobkov.
