摘要：In this talk，we discuss the stability and instability of trivial steady  state to the incompressible Navier-Stokes equations （with constant density）in a two dimensional slab domain with Navier boundary conditions. A sharp critical viscosity to distinquish the stability from the instability is exactly expressed in terms of the coeffcients in the Navier boundary conditions. The linear and the nonlinear stability and instability are analyzed. The decay estimates are also given. This is a joint work with Quanrong Li and Zhouping Xin.
