Many results given in this paper provide generalizations and extensions of the results given in previous research. Moreover, some examples are given to illustrate the investigated results.en10.1186/s13660-022-02896-9info:eu-repo/semantics/openAccessSimpson's Second Type; Preinvex Function; (P, Q)-Calculus; Q)-Differentiable Function; Q)-Integrable FunctionHermite-Hadamard Inequalities; Convex; CalculusArticle202212-s2.0-85144149776WOS:000912144900001Q2Q1
