We also derive post quantum Ostrowski-type inequalities for coordinated convex functions. Our significant results are considered as the generalizations of other results that appeared in the literature.en10.1002/mma.8748info:eu-repo/semantics/openAccessConvex Function; Coordinated Convex Function; Ostrowski Inequality; (P, Q)-Derivative; (P, Q)-Integral; (P, Q)-CalculusHadamard Inequality; Analogs; (PArticle2-s2.0-85138747103WOS:000859251100001Q1Q1
