An Optimal Control Problem Governed by a Kirchhoff-Type Variational Inequality

open access: yesJournal of Applied Mathematics, 2020
This paper is concerned with an optimal control problem governed by a Kirchhoff-type variational inequality. The existence of multiplicity solutions for the Kirchhoff-type variational inequality is established by using some nonlinear analysis techniques ...

Inequalities for the Generalized Normalized δ-Casorati Curvatures of Submanifolds in Golden Riemannian Manifolds

open access: yesAxioms, 2023
In the present article, we consider submanifolds in golden Riemannian manifolds with constant golden sectional curvature. On such submanifolds, we prove geometric inequalities for the Casorati curvatures.

On Weak Variational Control Inequalities via Interval Analysis

open access: yesMathematics, 2023
This paper deals with the connections between the interval-valued optimal control problem and the associated weak variational control inequality. More precisely, by considering the (strictly) LU-convexity and path independence properties of the involved ...

Analysis and control of a nonlinear boundary value problem

open access: yesNonlinear Analysis, 2017
We consider a nonlinear two-dimensional boundary value problem which models the frictional contact of a bar with a rigid obstacle. The weak formulation of the problem is in the form of an elliptic variational inequality of the second kind.
