Duality results for interval-valued semiinfinite optimization problems with equilibrium constraints using convexificators

Abstract

This paper deals with the study of interval-valued semiinfinite optimization problems with equilibrium constraints (ISOPEC) using convexificators. First, we formulate Wolfe-type dual problem for (ISOPEC) and establish duality results between the (ISOPEC) and the corresponding Wolfe-type dual under the assumption of ∂∗-convexity. Second, we formulate Mond–Weir-type dual problem and propose duality results between the (ISOPEC) and the corresponding Mond–Weir-type dual under the assumption of ∂∗-convexity, ∂∗-pseudoconvexity, and ∂∗-quasiconvexity. © 2022, The Author(s).
