Considering the methodology of discrete fractional calculus, we establish estimations of Gronwall type inequalities for unknown functions. These inequalities are of a new form comparative with the current writing discoveries up until this point and can be viewed as a supportive strategy to assess the solutions of discrete partial differential equations numerically. We show a couple of employments of the compensated inequalities to reflect the benefits of our work. The main outcomes might be demonstrated by the use of the examination procedure and the approach of the mean value hypothesis. © 2021, The Author(s).eninfo:eu-repo/semantics/openAccessDiscrete Fractional Difference InequalityFractional Difference EquationFractional Sum InequalityGronwall InequalityArticle2021110.1186/s13662-021-03257-4
