摘要: In the talk, I will report our recent study on the plane Couette flow of a rarefied gas between two
moving parallel infinite plates. In case of the Maxwell molecule collisions, we establish the existence
of spatially inhomogeneous nonequilibrium stationary solutions to the steady problem for any small
enough shear rate. The result indicates the polynomial tail at large velocities for the stationary
distribution. Moreover, the large time asymptotic stability of the stationary solution with an exponential convergence is also obtained through the study of the initial boundary value problem in the framework
of perturbation and as a consequence the nonnegativity of the steady profile is justified. This is a joint
work with Prof. R. Duan and Prof. T. Yang.
