一类三阶抛物双曲混合型偏微分方程的边值问题

Boundary Problem of a Class of the Parabolo-Hyperbolic Mixed Equation of ThirdOrder

本文研究三阶抛物双曲混合型方程带有边界条件的边值问题。文中证明了当且仅当α≠０时问题是适定的。

This paper studies the boundary problem for the parabolo-hyperbolic mixed equationof third orderunder the boundary conditions:It is proved in this paper that the problem is correct if and only if a≠0.
