Transversally Lipschitz harmonic functions are Lipschitz [PDF]
Let Ω\subset\mathbb{R}^n be a bounded domain with C^\infty boundary. We show that a harmonic function in Ωthat is Lipschitz along a family of curves transversal to bΩis Lipschitz in Ω. 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^α ...

Lipschitz continuous points of functions on an interval
In this paper, we address the problem of finding functions with predetermined Lipschitz continuous points. More precisely, given A⊆[0,1], we are interested in the existence of function f:[0,1]→R which is Lipschitz continuous exactly on A.

McShane-Whitney extensions in constructive analysis [PDF]
Within Bishop-style constructive mathematics we study the classical McShane-Whitney theorem on the extendability of real-valued Lipschitz functions defined on a subset of a metric space.

Lipschitz symmetric functions on Banach spaces with symmetric bases
We investigate Lipschitz symmetric functions on a Banach space $X$ with a symmetric basis. We consider power symmetric polynomials on $\ell_1$ and show that they are Lipschitz on the unbounded subset consisting of vectors $x\in \ell_1$ such that $|x_n ...

CONTROLLING LIPSCHITZ FUNCTIONS [PDF]
Given any positive integers $m$ and $d$, we say the a sequence of points $(x_i)_{i\in I}$ in $\mathbb R^m$ is {\em Lipschitz-$d$-controlling} if one can select suitable values $y_i\; (i\in I)$ such that for every Lipschitz function $f:\mathbb R^m\rightarrow \mathbb R^d$ there exists $i$ with $|f(x_i)-y_i|<1$. We conjecture that for every $m\le d$, a

Lipschitz differences and Lipschitz functions [PDF]
Let \(G\) be any of the groups \(R\) or \(T= R/Z\) (the circle group) and, for every \(L >0\), set \( \text{ Lip}_L(G) = \{g:G \to R\;\text{ such \;that \;} |g(x)-g(y)|\leq L |x-y|\;\forall x,y \in G\}, \;\text{ Lip}(G) = \bigcup_{L>0} \text{ Lip}_L(G)\).

Approximate tri-quadratic functional equations via Lipschitz conditions [PDF]
In this paper, we consider Lipschitz conditions for tri-quadratic functional equations. We introduce a new notion similar to that of the left invariant mean and prove that a family of functions with this property can be approximated by tri-quadratic ...

Lipschitz Bernoulli Utility Functions
We obtain several variants of the classic von Neumann–Morgenstern expected utility theorem with and without the completeness axiom in which the derived Bernoulli utility functions are Lipschitz. The prize space in these results is an arbitrary separable metric space, and the utility functions are allowed to be unbounded.

Characterization of Lipschitz Spaces via Commutators of Maximal Function on the p-Adic Vector Space
In this paper, we give characterization of a p-adic version of Lipschitz spaces in terms of the boundedness of commutators of maximal function in the context of the p-adic version of Lebesgue spaces and Morrey spaces, where the symbols of the commutators
