In the present paper, we generalize the concept of well-posedness to a hemivariational
inequality, give some metric characterizations of the wellposed hemivariational inequality …

We discuss the well-posedness and the well-posedness in the generalized sense of
differential mixed quasi-variational inequalities ((DMQVIs), for short) in Hilbert spaces. This …

We consider well-posedness under perturbations of vector quasiequilibrium and bilevel-
equilibrium problems. This kind of well-posedness relates Hadamard and Tikhonov well …

Bilevel equilibrium and optimization problems with equilibrium constraints are considered.
We propose a relaxed level closedness and use it together with pseudocontinuity …

In this paper, we first revisit the parametric bilevel vector equilibrium problems in Hausdorff
topological vector spaces. Then we study the stability conditions such as (Hausdorff) upper …

In this paper, we establish sufficient conditions for the approximate solution mappings of
parametric bilevel equilibrium problems with stability properties such as upper …

In this paper we consider the Levitin–Polyak well-posedness of variational inequalities. We
derive a characterization of the Levitin–Polyak well-posedness by considering the size of …

In this paper, we establish the Hölder continuity of solution mappings to parametric vector
quasiequilibrium problems in metric spaces under the case that solution mappings are set …

In this paper, we consider the well-posedness of mixed quasi-variational-hemivariational
inequalities ((MQVHVI) for short). By introducing a new concept of the α-η-monotone …

The aim of this work is to investigate optimization-related problems with the objective spaces
ordered by the lexicographic cones, including parametric lexicographic equilibrium …
