(2009-6161) Interval discrete fractional calculus and its application to interval fractional difference equations
R. Beigmohamadi, Alireza Khastan · Iranian journal of fuzzy systems · 2021
In this work, we present some useful results of discrete fractional calculus for interval-valued functions. The composition rules for interval fractional operators are introduced, which are used to construct the general form of the solutions tononlinear interval fractional difference equations. An illustrative example is provided in which the method of recursive iterations is applied to obtain explicit formulas for the solutions of linear interval fractional difference equations.
