混合型方程组的Dirichlet边界值问题(英文)

ON DIRICHLET BOUNDARY VALUE PROBLEMS OF MIXED-TYPE EQUATIONS

在管道中的超音速流是与混合型方程组紧密相关的.本文通过能量积分方法与Riesz表示定理,得到了一些混合型方程组的闭边界值问题的解的存在性.

In this paper, we focus on the mixed-type equations which are closely related to continuous transonic flows in the nozzles. By use of the energy integral method and Riesz representation theorem, we establish the existence of solutions to the closed boundary value problems of some mixed-type equations.
