## Existence and approximation of solutions of some first order iterative differential equations.(English)Zbl 1224.34014

Summary: Existence theorems for some iterative differential equations as well as convergence theorems for an iterative method designed to approximate these solutions, are proved. To this end, we basically employ the technique of non-expansive mappings.
