“…Motivated by this observation, Levitin and Polyak [21] introduced an alternative notion of wellposedness, say Levitin-Polyak (LP) well-posedness, which strengthened the Tykhonov one. There have recently been many papers in the literature dealing with LP wellposedness for optimization problems with functional and/or geometric constraints, variational inequalities, equilibrium problems, bilevel mathematical programs; see, for instance, [5,12,13,28,33].…”

This article aims to elaborate on various notions of Levitin-Polyak well-posedness for set optimization problems concerning Pareto efficient solutions. These notions are categorized into two classes including pointwise and global Levitin-Polyak well-posedness. We give various characterizations of both pointwise and global Levitin-Polyak well-posedness notions for set optimization problems. The hierarchical structure of their relationships is also established. Under suitable conditions on the input data of set optimization problems, we investigate the closedness of Pareto efficient solution sets in which they are different from the weakly efficient ones. Furthermore, we provide sufficient conditions for global Levitin-Polyak well-posedness properties of the reference problems without imposing the information on efficient solution sets.
