The oscillation of separately locally Lipschitz functions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We prove that a function which dened on the product of two metric Baire spaces is the oscillation of some separately locally Lipschitz function if and only if it is an upper semicontinuous non-negative function which has a crosswise nowhere dense closure

Almost sure and moment exponential stability in the numerical simulation of stochastic differential equations [PDF]

open access: yes, 2007
Relatively little is known about the ability of numerical methods for stochastic differential equations (SDEs) to reproduce almost sure and small-moment stability.

Semilinear Poisson problems in Sobolev-Besov spaces on Lipschitz domains [PDF]

open access: yes, 2002
Extending recent work for the linear Poisson problem for the Laplacian in the framework of Sobolev-Besov spaces on Lipschitz domains by Jerison and Kenig [16], Fabes, Mendez and Mitrea [9], and Mitrea and Taylor [30], here we take up the task of ...

Distributed convex optimization via proportional-integral-differential algorithm

open access: yesMeasurement + Control, 2022
This paper studies the distributed convex optimization problem, where the global utility function is the sum of local cost functions associated to the individual agents.

Existence of fixed points on compact epilipschitz sets without invariance conditions

open access: yesFixed Point Theory and Applications, 2005
We provide a new result of existence of equilibria of a single-valued Lipschitz function f on a compact set K of ℝn which is locally the epigraph of a Lipschitz functions (such a set is called epilipschitz set).

Discretization methods for nonconvex differential inclusions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
We prove the existence of solutions for the differential inclusion $\dot x(t)\in F(t,x(t)) + f(t,x(t))$ for a multifunction $F$ upper semicontinuous with compact values contained in the generalized Clarke gradient of a regular locally Lipschitz function ...

On compactness and connectedness of the paratingent [PDF]

open access: yes, 2016
In this note we shall prove that for a continuous function \(\varphi : \Delta\to\mathbb{R}^n\), where \(\Delta\subset\mathbb{R}\),  the paratingent of \(\varphi\) at \(a\in\Delta\) is a non-empty and compact set in \(\mathbb{R}^n\) if and only if ...

A Multiplicity Theorem for Locally Lipschitz Periodic Functionals

open access: yesJournal of Mathematical Analysis and Applications, 1995
The authors consider the periodic multivalued problem of the forced pendulum \[ \begin{cases} x''(t) + f(t)\in \biggl[\underline g\bigl(x(t) \bigr), \overline g \bigl(x(t) \bigr)\biggr], \quad \text{a.e. } t\in(0,1) \\ x(0) = x(1),\;x'(0) = x'(1) \end{cases} \] where \(f\in L^p(0,1)\), \(g\in L^\infty (\mathbb{R})\) is periodic of period \(T\), the ...

Some Inexact Version of the Iterative Exponential Method for Solving Nonsmooth Equations

open access: yesAlgorithms, 2023
This paper presents an inexact version of an exponential iterative method designed for solving nonlinear equations F(x)=0, where the function F is only locally Lipschitz continuous.
