Characterization of the Local Lipschitz Constant

open access: yesJournal of Approximation Theory, 1994
Let \(X\) be a closed subset of \([a,b]\) with at least \(n+1\) points, and let \(C(X)\) denote the space of continuous real valued functions on \(X\) endowed with the uniform norm. Let \(H_ n\) denote a Haar set of dimension \(n\), and let the best approximation of \(f\in C(X)\) in \(H_ n\) be \(B_ n(f)\).

Multiple Solutions for Nonhomogeneous Neumann Differential Inclusion Problems by the p(x)-Laplacian

open access: yesThe Scientific World Journal, 2013
A class of nonlinear Neumann problems driven by p(x)-Laplacian with a nonsmooth locally Lipschitz potential (hemivariational inequality) was considered. The approach used in this paper is the variational method for locally Lipschitz functions.

Local Lipschitz constants

open access: yesJournal of Approximation Theory, 1985
Let X be a closed subset of \(I=[-1,1]\). For \(f\in C[X]\), the local Lipschitz constant is defined to be \(\lambda_{n\delta}(f)=\sup \{\| B_ n(f)-B_ n(g)\| /\| f-g ...

Nonsmooth analysis and optimization on partially ordered vector spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
Interval-Lipschitz mappings between topological vector spaces are defined and compared with other Lipschitz-type operators. A theory of generalized gradients is presented when both spaces are locally convex and the range space is an order complete vector

A NEW PROOF OF CLARKE'S THEOREM

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2012

Purely 1-Unrectifiable Metric Spaces and Locally Flat Lipschitz Functions [PDF]

open access: yes, 2021
International audienceFor any compact metric space M , we prove that the locally flat Lipschitz functions separate points (of M) uniformly if and only if M is purely 1-unrectifiable, resolving a problem posed by Weaver in 1999.

Local and global Lipschitz constants

open access: yesJournal of Approximation Theory, 1986
Let X be a closed subset of [-1,1] which contains at least \(n+2\) points, and let \(B_ n(f)\) be the best uniform approximation to \(f\in C[X]\) from the set \(\pi_ n\) of all polynomials of degree at most n. The global Lipschitz constant of f is defined as \[ \lambda_ n(f)=\sup \{\| B_ n(f)-B_ n(g)\| /\| f-g\|:g\in C[X],g\neq f\}, \] and the strong ...
