Some estimates for commutators of bilinear pseudo-differential operators

open access: yesOpen Mathematics, 2022
We obtain a class of commutators of bilinear pseudo-differential operators on products of Hardy spaces by applying the accurate estimates of the Hörmander class. And we also prove another version of these types of commutators on Herz-type spaces.

Vector-valued optimal Lipschitz extensions [PDF]

open access: yes, 2010
Consider a bounded open set $U$ in $R^n$ and a Lipschitz function g from the boundary of $U$ to $R^m$. Does this function always have a canonical optimal Lipschitz extension to all of $U$?

Optimal Lipschitz extensions

open access: yesITM Web of Conferences, 2018
The classical Lipschitz extension problem in concerned for conditions on a pair of metric spaces (X,dX) and (Y,dY) such that for all Ω ⊂ X and for all Lipschitz function and for all Lipschitz function f : Ω → Y, then there is a function g : X → Y that ...

Optimality Conditions, Qualifications and Approximation Method for a Class of Non-Lipschitz Mathematical Programs with Switching Constraints

open access: yesMathematics, 2021
In this paper, we consider a class of mathematical programs with switching constraints (MPSCs) where the objective involves a non-Lipschitz term. Due to the non-Lipschitz continuity of the objective function, the existing constraint qualifications for ...

Monotonicity preserving approximation of multivariate scattered data [PDF]

open access: yes, 2005
This paper describes a new method of monotone interpolation and smoothing of multivariate scattered data. It is based on the assumption that the function to be approximated is Lipschitz continuous.

Transversally Lipschitz harmonic functions are Lipschitz [PDF]

open access: yesComplex Variables and Elliptic Equations, 2013
Let \subset\mathbb{R}^n be a bounded domain with C^\infty boundary. We show that a harmonic function in that is Lipschitz along a family of curves transversal to b is Lipschitz in . The space of Lipschitz functions we consider is defined using the notion of a majorant which is a certain generalization of the power functions t ...

Complementary Lipschitz continuity results for the distribution of intersections or unions of independent random sets in finite discrete spaces [PDF]

open access: yes, 2019
We prove that intersections and unions of independent random sets in finite spaces achieve a form of Lipschitz continuity. More precisely, given the distribution of a random set $\Xi$, the function mapping any random set distribution to the distribution ...
