Abstract
This article investigates stability conditions for set optimization problems with the set
less order relation in the senses of Panilevé–Kuratowski and Hausdorff convergence.
Properties of various kinds of convergences for elements in the image space are dis-
cussed. Taking such properties into account, formulations of internal and external
stability of the solutions are studied in the image space in terms of the convergence
of a solution sets sequence of perturbed set optimization problems to a solution set of
the given problem.

1 Introduction
Set-valued optimization is an interesting and important branch of applied mathematics,
that is designed to solve optimization problems, in which either the objective mapping
or the constraint mappings are set-valued mappings acting between abstract spaces.
Concerning set-valued optimization, there are two main approaches, depending on
what the notion of minimality is considered. The classical one is vector approach,
where the definition of a minimizer considers only an efficient point of the union of
all images of the set-valued objective mapping and identifies the image set containing
this minimal element as the “best” available [1,2]. However, a serious disadvantage of
this approach is that, in general, only one element does not necessarily imply that the
