| Abstract: | The present paper deals with oblique derivative problems for second order equations of mixed type with degenerate rank 0, which include the Tricomi problem for the Chaplygin equation in gas dynamics as a special case. By using the complex analytic method, the uniqueness of solutions of above boundary value problems is proved. |
