タイトル Gevrey stability of shear boundary layer for two dimensional Navier-Stokes flow 2019年12月11日 16:45 ～ 前川 泰則 氏（京大・理） 慶應義塾大学理工学部 14棟 733 (創想館 7階 ミーティング3) We investigate the stability of boundary layer solutions in the inviscid limit for the two dimensional incompressible Navier-Stokes equations. We prove that, if the shear boundary layer is monotonic and concave, then it is stable in the inviscid limit over some time interval under perturbations with some Gevrey regularity. The proof relies on the resolvent analysis for the Orr-Sommerfeld operator. This talk is based on a joint work with David Gerard-Varet (Paris 7) and Nader Masmoudi (NYU).
