First order optimality conditions in set-valued optimization [PDF]

A a set-valued optimization problem minC F(x), x 2 X0, is considered, where X0 X, X and Y are Banach spaces, F : X0 Y is a set-valued function and C Y is a closed cone.

Rational choice by two sequential criteria [PDF]

This paper contributes to the theory of rational choice under multiple criteria. We perform a preliminary study of the properties of decision made by the sequential application of rational choices.

Existence results for second order convex sweeping processes in p-uniformly smooth and q-uniformly convex Banach spaces

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In a previous work the authors proved under a complex assumption on the set-valued mapping, the existence of Lipschitz solutions for second order convex sweeping processes in $p$-uniformly smooth and $q$-uniformly convex Banach spaces.

P-Algebras

Axioms
Following the notions of Ω-set and Ω-algebra where Ω is a complete lattice, we introduce P-algebras, replacing the lattice Ω by a poset P. A P-algebra is a classical algebraic structure in which the usual equality is replaced by a P-valued equivalence ...

Korovkin Approximation for Weighted Set-Valued Functions

Journal of Approximation Theory, 1999
The author studies the existence of Korovkin systems in the general setting of weighted spaces of continuous functions defined on a locally compact Hausdorff space \(X\) and with values in the set of non-empty compact convex subsets of a locally convex space \(E.\) One gives a Korovkin type approximation theorem for monotone linear operators on such ...

On Solutions of Two Post-Quantum Fractional Generalized Sequential Navier Problems: An Application on the Elastic Beam

Fractal and Fractional
Fractional calculus provides some fractional operators for us to model different real-world phenomena mathematically. One of these important study fields is the mathematical model of the elastic beam changes.

Existence of convex and non convex local solutions for fractional differential inclusions

Electronic Journal of Differential Equations, 2009
In this paper, we establish the existence theorems for a class of fractional differential inclusion of order $n-1 < alpha leq n $. The study holds in two cases, when the set-valued function has convex and non-convex values.
