As a byproduct, we get the existence result of classical solutions to the stationary quantum Navier-Stokes equations.展开更多

In this paper, we study stationary problem of the model subject to the homogeneous Neumann boundary conditions. We derive some existence results of the non-constant solutions of the stationary problem based on Priori estimations and Topological Degree theory. The existence of non-constant stationary solutions implies the existence of spatially variant time invariant solutions for the model.展开更多
