On solutions of a class of systems of nonlinear functional differential equations of neutral type with complicated deviations of an argument

摘要

Sufficient conditions for the existence of a unique bounded solution together with its first derivative on~(R+) of a system of nonlinear functional differential equations with an iterated deviating argument dependent of unknown function, and satisfying the condition limt~→_+∞|x(t+1)-x(t)|=0, are given.
