报告简介

Consider the linear stability of the three dimensional isentropic compressible Navier-Stokes equations on T×R×T. We prove the enhanced dissipation phenomenon for the linearized isentropic compressible Navier-Stokes equations around the Couette flow (y, 0, 0). Moreover, the lift-up phenomenon is also shown in this paper. Compared with the 3D incompressible Navier-Stokes equations [Ann. of Math.,185(2017), 541--608], the lift-up effect here is stronger due to the loss of the incompressible condition. This is based on a joint work with Lan Zeng and Zhifei Zhang.
