Existence of positive solution to a coupled system of singular fractional difference equations via fractional sum boundary value conditions
Abstract In this article, we study a coupled system of singular fractional difference equations with fractional sum boundary conditions. A sufficient condition of the existence of positive solutions is established by employing the upper and lower solutions of the system and using Schauder’s fixed po...
