Constrained nonsmooth problems of the calculus of variations [PDF]
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. To derive optimality conditions, we study generalised concepts of differentiability of nonsmooth functions ...

Generalized Differential Calculus for Nonsmooth and Set-Valued Mappings
Some generalized differentiability concepts for multifunctions and nonsmooth mappings in \(\mathbb{R}^ n\) are studied. In this paper the most important one is the so-called coderivative of multifunctions introduced earlier [the author, Dokl. Akad. Nauk SSSR 254, 1072-1076 (1980; Zbl 0491.49011)] using the normal cone to the graph in the sense given by

Asymptotic stationarity and regularity for nonsmooth optimization problems [PDF]
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

We survey recent advances in analysis and geometry, where first order differential analysis has been extended beyond its classical smooth settings. Such studies have applications to geometric rigidity questions, but are also of intrinsic interest. The transition from smooth spaces to singular spaces where calculus is possible parallels the classical ...

Nonsmooth Calculus in Finite Dimensions
New calculus rules are given for the Clarke generalized gradient \(\partial f\) of a general lower semicontinuous function \(f: {\mathbb{R}}^ n\to {\mathbb{R}}\cup \{\pm \infty \}\). These include rules for computing \(\partial f\) when \(f=f_ 1+f_ 2\circ F\) in cases where \(f_ 1\), \(f_ 2\) are l.s.c. and F is either stricly differentiable or isotone.

Proximal Bundle Method for Contact Shape Optimization Problem
From the mathematical point of view, the contact shape optimization is a problem of nonlinear optimization with a specific structure, which can be exploited in its solution. In this paper, we show how to overcome the difficulties related to the nonsmooth

Restrictive metric regularity and generalized differential calculus in Banach spaces
We consider nonlinear mappings f:X→Y between Banach spaces and study the notion of restrictive metric regularity of f around some point x¯, that is, metric regularity of f from X into the metric space E=f(X).

After more than a century of unremitting efforts by scholars, nonlinear analysis has found widespread and important applications in many fields that are at the core of many branches of pure and applied mathematics, including functional analysis, fixed ...

This paper explores fractional-order complex-valued neural networks (FOCVNNs) with time delays and discontinuous activation functions. A novel fractional-order inequality is utilized to study this system as a whole without dividing it into different ...

On solutions of Hamilton-Jacobi equations with exponential dependence on momentum
Three initial problems for one-dimensional Hamilton-Jacobi equations of evolutionary type are considered on a bounded time segment. In all problems, the Hamiltonians depend on the coordinate and momentum variables.
