Abstract


In this paper, we define and introduce some new concepts of the
higher order strongly generalized preinvex functions and higher order strongly monotone operators involving the arbitrary bifunction and function. Some new relationships among various concepts of higher order strongly general preinvex functions have been established. It is shown that the optimality conditions of the higher order strongly general preinvex functions are characterized by a class of variational inequalities, which is called the higher order strongly
generalized variational-like inequality. Auxiliary principle technique is used to suggest an implicit method for solving strongly generalized variational-like inequalities. Convergence analysis of the proposed method is investigated using the pseudo-monotonicity of the operator. It is shown that the new parallelogram laws for Banach spaces can be obtained as applications of higher order strongly affine generalized preinvex functions, which is itself an novel application. Some special cases also discussed. Results obtained in this paper can be viewed as refinement and improvement of previously known results.
