| Abstract: | This paper mainly deals with oblique derivative problems for second order equations of hyperbolic and mixed type with parabolic degenearcy. Firstly the above problem for hyperbolic equations is introduced, and then the above problem for mixed equations is considered. The complex analytic method is used through the paper. |
