Additionally, Holder's and Power mean inequalities involving q-symmetric integral are powerful tools to prove the results. Certain novel Ostrowski type inequalities for P-convex function, s-convex function, Godunova levin function, and s-Godunova Levin function are established, which are special instances of inequalities found for h-convex functions. Some examples are also provided along with graphical illusions to demonstrate the validity of the new discoveries. Our findings are regarded as generalizations of some known inequities from the literature.en10.2298/FIL2433951Ninfo:eu-repo/semantics/openAccessConvex functionh-convex functionquantum calculusquantum symmetric variational calculusOstrowski type inequalitiesArticle383311951119672-s2.0-85216505816WOS:001468185400023Q3Q2
