The existence of solutions for the given problem is proven by applying Krasnoselskii’s fixed-point theorem and the Leray–Schauder alternative. In contrast, the uniqueness of the solutions is established by employing Banach’s contraction mapping principle. Examples illustrating the main results are also presented.

Fractionalq-calculus has been investigated and applied in a variety of research subjects including the fractionalq-trapezoid andq-midpoint type inequalities. Fractional$(p,q)$(p,q)-calculus on finite intervals, particularly the fractional$(p,q)$(p,q)-integral inequalities, has been studied. In this paper, we study two identities for continuous functions in the form of fractional$(p,q)$(p,q)-integral on finite intervals. Then, the obtained results are used to derive some fractional$(p,q)$(p,q)-trapezoid and$(p,q)$(p,q)-midpoint type inequalities.

In this paper, we study fractional (p,q)-calculus on finite intervals and give some basic properties. In particular, some fractional (p,q)-integral inequalities on finite intervals are proven.
