This article discusses the existence of positive solutions to Sturm–Liouville boundary value problems for Riemann–Liouville nabla fractional difference equations. The results obtained here shall generalize the existing ones. We provide a few examples to illustrate the applicability of established results.
Keywords: Riemann–Liouville fractional difference, cone
Mots-clés : Sturm–Liouville problem, existence, positive solution.
