Convergence in approximation and nonsmooth analysis

Journal of Approximation Theory, 1987
The authors examine some stability questions associated with problems in approximation theory and nonsmooth analysis. They study what happens to various sets that often appear in those fields, when one perturbs in some sense the data determining them. Such sensitivity analysis is important for developing efficient numerical algorithms.

Necessary optimality conditions for two-step descriptor systems

AIMS Mathematics, 2022
This paper is concerned with an optimal control problem for general two-step descriptor systems. Based on the nonsmooth analysis and variational techniques, we establish the first-order necessary optimality conditions.

Bolza type problems in infinite dimensional discrete time [PDF]

Journal of Hyperstructures, 2013
In this paper we study a discrete time version of deterministic models in optimization in infinite dimensional. The functionals are assumed to be merely lower semi continuous.

Semidefinite Multiobjective Mathematical Programming Problems with Vanishing Constraints Using Convexificators

Fractal and Fractional, 2021
In this paper, we establish Fritz John stationary conditions for nonsmooth, nonlinear, semidefinite, multiobjective programs with vanishing constraints in terms of convexificator and introduce generalized Cottle type and generalized Guignard type ...

Constrained Nonsmooth Problems of the Calculus of Variations

, 2021
The paper is devoted to an analysis of optimality conditions for nonsmooth multidimensional problems of the calculus of variations with various types of constraints, such as additional constraints at the boundary and isoperimetric constraints.

Stability and Periodic Motions for a System Coupled with an Encapsulated Nonsmooth Dynamic Vibration Absorber

Applied Sciences, 2023
The dynamic vibration absorber (DVA) is widely used in engineering models with complex vibration modes. The research on the stability and periodic motions of the DVA model plays an important role in revealing its complex vibration modes and energy ...

Duality for nonsmooth mathematical programming problems with equilibrium constraints

Journal of Inequalities and Applications, 2016
In this paper, we consider the mathematical programs with equilibrium constraints (MPECs) in Banach space. The objective function and functions in the constraint part are assumed to be lower semicontinuous.
