利用Schauder不动点定理,证明了具有混合边界条件的三维非齐次定常Navier-Stokes方程弱解的存在性。混合边界条件由Dirichlet边界条件和自然边界条件所组成。
In this paper,in view of the Schauder fixed point theorem,we show the existence of weak solution of three dimensional nonhomogeneous steady Navier-Stokes equations with mixed boundary conditions which are composed of the Dirichlet boundary condition and the natural boundary condition.
