本文主要给出一般区域上的Darboux第二问题与一般斜微商问题解的表示式,进而使用复分析的方法证明了这些问题解的存在性与唯一性。本文中得到的结果,可用来解决一般区域上的广义chaplygin方程的Tricomi问题。
The present paper deals with some boundary value problems for the degenerate hy- perbolic equations of second order,mainly the representation of solutions for Darboux~s sec- ond problem and general oblique derivative problem in general domains is given, and the exist- ence and uniqueness of solutions for the problems are proved. The results in this paper can be used to solve Tricomi problem of generalized Chaplygin equations in general domains.
