Nonsmooth Analysis [PDF]

open access: yes, 1984
This survey of nonsmooth analysis sets out to prove an inverse function theorem for set-valued maps. The inverse function theorem for the more usual smooth maps plays a very important role in the solution of many problems in pure and applied analysis ...

Smoothed quantile residual life regression analysis with application to the Korea HIV/AIDS cohort study [PDF]

open access: yesBMC Medical Research Methodology
Background The residual life of a patient with human immunodeficiency virus (HIV) is of major interest to patients and their physicians. While existing analyses of HIV patient survival focus mostly on data collected at baseline, residual life analysis ...

Bolza type problems in infinite dimensional discrete time [PDF]

open access: yesJournal 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

open access: yesFractal 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

open access: yes, 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

open access: yesApplied 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 ...

Asymptotic stationarity and regularity for nonsmooth optimization problems [PDF]

open access: yesJournal of Nonsmooth Analysis and Optimization, 2020
Based on the tools of limiting variational analysis, we derive a sequential necessary optimality condition for nonsmooth mathematical programs which holds without any additional assumptions. In order to ensure that stationary points in this new sense are

An Analysis of the Rayleigh-Stokes problem for a Generalized Second-Grade Fluid [PDF]

open access: yes, 2015
We study the Rayleigh-Stokes problem for a generalized second-grade fluid which involves a Riemann-Liouville fractional derivative in time, and present an analysis of the problem in the continuous, space semidiscrete and fully discrete formulations.

Duality for nonsmooth mathematical programming problems with equilibrium constraints

open access: yesJournal 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.

Investigation of the Effect of Dimple Bionic Nonsmooth Surface on Tire Antihydroplaning

open access: yesApplied Bionics and Biomechanics, 2015
Inspired by the idea that bionic nonsmooth surfaces (BNSS) reduce fluid adhesion and resistance, the effect of dimple bionic nonsmooth structure arranged in tire circumferential grooves surface on antihydroplaning performance was investigated by using ...
