Prederivatives of gamma paraconvex set-valued maps and Pareto optimality conditions for set optimization problems [PDF]
Journal of Inequalities and Applications, 2017 Prederivatives play an important role in the research of set optimization problems. First, we establish several existence theorems of prederivatives for γ-paraconvex set-valued mappings in Banach spaces with γ > 0 $\gamma>0$ .

Approximate Convexity for Set-Valued Maps [PDF]
Mathematics Interdisciplinary Research, 2023 In this paper, we extend the notion of approximate convexity to set-valued maps and obtain some relations between approximate convexity and approximate monotonicity of their normal subdifferential.

On Fixed Points of Soft Set-Valued Maps
Fuzzy Optimization and Modeling, 2021 Conventional mathematical tools which require all inferences to be exact, are not always sufficient to handle imprecisions in a wide variety of practical fields. Thus, among various developments in fuzzy mathematics, enormous efforts have been in process

Using ρ-cone arcwise connectedness on parametric set-valued optimization problems
Journal of Inequalities and Applications, 2022 Within the inquiry about work, we explore a parametric set-valued optimization problem, where the objective as well as constraint maps are set-valued.

On Fuzzy Soft Set-Valued Maps with Application
Journal of Nigerian Society of Physical Sciences, 2020 Soft set and fuzzy soft set theories are proposed as mathematical tools for dealing with uncertainties. There has been tremendous progress concerning the extensions of these theories from different point of views of researchers so as to accommodate more ...

Structure of the Fixed Point of Condensing Set-Valued Maps [PDF]
Mathematics Interdisciplinary Research, 2020 In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.

Stable approximations of set-valued maps [PDF]
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 1988 The celebrated Lax’ principle “stability and consistency implies convergence” is adapted to the case of nonlinear equation and even inclusions (multivalued equations) through a convenient concept of stability. It requires the definition of “contingent derivative” of single or set-valued maps and states that a family of maps is stable if and only if the
