| Abstract: | In this paper we investigate the singularly perturbed Picard and Neumann problems. Under the appropriate assumptions,by means of the theory of differential inequality, we directly give out the existence of solutions and the estimations of solutions and its differential coefficient of the problems discribed. Hence. It has offered one kind of method which is applied to investigate the estimations of solutions for the singularly perturbed problems. |
