Viable solutions to nonautonomous inclusions without convexity [PDF]

, 2003
The existence of viable solutions is proven for nonautonomous upper semicontinuous differential inclusions whose right-hand side is contained in the Clarke subdifferential of a locally Lipschitz continuous ...

Optimality and scalarization of robust approximate solutions for semi-infinite vector equilibrium problems

Journal of Inequalities and Applications
This paper investigates the optimality conditions and scalarization theorems for robust approximate solutions to semi-infinite vector equilibrium problems with data uncertainty in the constraints.

Solvability of a New Class of ψ-Fractional Unilateral Constrained Friction Problems

Fractal and Fractional
A new type of frictional contact problem is proposed in this paper. The nonlinear viscoelastic constitutive relationship we are considering contains ψ-fractional differential terms.

Derivatives of orbital function and an extension of Berezin-Gel’fand’s theorem

Special Matrices, 2016
A generalization of a result of Berezin and Gel’fand in the context of Eaton triples is given. The generalization and its proof are Lie-theoretic free and requires some basic knowledge of nonsmooth analysis.

Distinct Differentiable Functions May Share the Same Clarke Subdifferential at All Points

, 1995
. We construct, using Zahorski's Theorem, two everywhere differentiable real--valued Lipschitz functions differing by more than a constant but sharing the same Clarke subdifferential and the same approximate subdifferential.

Three nontrivial solutions for nonlocal anisotropic inclusions under nonresonance

Electronic Journal of Differential Equations, 2019
In this article, we study a pseudo-differential inclusion driven by a nonlocal anisotropic operator and a Clarke generalized subdifferential of a nonsmooth potential, which satisfies nonresonance conditions both at the origin and at infinity. We prove

Approximate controllability of impulsive neutral fractional hemivariational inequalities involving memory term

Nonlinear Analysis
This paper develops a new analytical framework for impulsive neutral fractional differential systems with memory terms. Fractional calculus is adopted for its superior capability in capturing hereditary and memory effects commonly observed in complex ...

Generalization of Clark’s derivation and subdifferential [PDF]

, 2009
In this talk, we first introduce some new concepts of nonsmooth analysis for locally convex topological vector spaces and then by using these definition we obtain some results. Moreover we generalizes Lebourg’s mean value theorem to locally convex spaces.
