| Abstract: | Cauchy problems of singular perturbation type for nonlinear differential equations in Benach spaces are studied.The existence result and the asymptotic estimates of the solution in the maximum norm are examined by means of some fixed point theorems. |
| |
| Keywords: | singular perturbation asymptotic estimates supersolution lower solution |
