In this paper, we establish a new (p,q)-integral identity using twice (p,q)-differentiable convex functions. Then, we use this result to derive some new post-quantum Ostrowski-type integral inequalities for twice (p,q)-differentiable convex functions. The newly established results are also proven to generalize some existing results in the area of integral inequalities of already published ones.

In this paper, we establish a new post quantum integral identity for twice $(p,q)$-differentiable convex functions. Then, we use this result to derive some new post quantum Ostrowski-type inequalities for twice $(p,q)$-differentiable convex functions involving $(p,q)_a$- and $(p,q)^b$-integrals. The newly established results are also proven to be generalizations of some existing results in the field of integral inequalities of already published ones.
