An ordinary integro-differential equation with a degenerate kernel and an integral condition

We consider the questions of one value solvability of the nonlocal boundary value problem for a nonlinear ordinary integro-differential equation with a degenerate kernel and a reflective argument. The method of the degenerate kernel is developed for the case of considering ordinary integro-differential equation of the first order. After denoting the integro-differential equation is reduced to a system of algebraic equations with complex right-hand side. After some transformation we obtaine the nonlinear functional-integral equation, which one valued solvability is proved by the method of successive approximations combined with the method of compressing mapping. This paper advances the theory of nonlinear integro-differential equations with a degenerate kernel.
