The bounds for both left-hand and right-hand sides of the integral inequality are established for operator (ω1,ω2)-preinvex functions of the positive self-adjoint operator in the complex Hilbert spaces. We give the special cases to our results; thus, the established results are generalizations of earlier work. In the last section, we give applications for synchronous (asynchronous) functions.enHermite–Hadamard inequalitiesHermite–Hadamard–Fejér inequalities(ω1,ω2)-preinvexityself-adjoint operatorspositive operatorsfunctions of self-adjoint operatorsHölder inequalitysynchronous (asynchronous) functionsFejér-Type Midpoint and Trapezoidal Inequalities for the Operator ω1,ω2-Preinvex FunctionsArticle
