【Abstract】 All known functions being Hlder continuous in a connected region EC, we discuss the stability of Riemann boundary value problem when the smooth perturbation of boundary curve occurs,and give the corresponding error estimates. Finally we establish a convergent theorem and put forward a conception of perturbation quasi-solvability when the index of Riemann boundary problem is less than zero.更多还原
