Existence of solutions for a coupled system of difference equations with causal operators
In this paper, we discuss a coupled system of difference equations with causal operators. Sufficient conditions under which such problems have solutions are given, by using a monotone iterative method. Difference inequalities with causal operators are also investigated. An example illustrates the re...
