Moreover, we discuss several special cases of newly established inequalities and obtain different new and existing inequalities in the field of integral inequalities. © 2021 Thanin Sitthiwirattham et al., published by De Gruyter.All Open Access; Gold Open Accessconvex functionsdifference operatorsintegral inequalitiesOstrowski inequalitiesq-integralquantum calculusArticleScopus
