We establish some new post-quantum Ostrowski type inequalities for differentiable coordinated functions using the newly established equality. We also show that the results presented in this paper are the extensions of some existing results.en10.3934/math.2022448info:eu-repo/semantics/openAccessOstrowski Inequality; (P, Q)-Integrals; Post-Quantum Calculus; Co-Ordinated Convex FunctionMidpoint-Type Inequalities; Hermite-Hadamard Inequalities; Convex; (PArticle75803580632-s2.0-85126839995WOS:000794129400005Q2Q1
