New post quantum analogues of Ostrowski-type inequalities using new definitions of left–right (p,q)-derivatives and definite integrals.

The main objective of this paper is to introduce a new more elegant notion of left–right (p , q) -derivative and definite integrals. To show the significance of these concepts, we discuss some of their basic properties. A new generalized (p , q) -integral identity is also obtained. Utilizing this identity as an auxiliary result we then obtain our main results using the concept of n-polynomial convex functions. [ABSTRACT FROM AUTHOR]
