چکیده
We extend the recent result of G. Godefroy which concerns existence non-norm attaining Lipschitz maps in order to characterize norm attainment toward vectors for general setting underlying space. The main theorem present paper states that on a large class metric spaces is characterized by finite-dimensionality range As an extension his counterexample, some denseness results are also shown.

lipschitz groups and lipschitz maps
this contribution mainly focuses on some aspects of lipschitz groups, i.e., metrizable groups with lipschitz multiplication and inversion map. in the main result it is proved that metric groups, with a translation-invariant metric, may be characterized as particular group objects in the category of metric spaces and lipschitz maps. moreover, up to an adjustment of the metric, a...
متن کاملNorm Attaining Multilinear Forms on L1(μ)
Given an arbitrary measure μ, this study shows that the set of norm attaining multilinear forms is not dense in the space of all continuous multilinear forms on L1 μ . However, we have the density if and only if μ is purely atomic. Furthermore, the study presents an example of a Banach space X in which the set of norm attaining operators from X into X∗ is dense in the space of all bounded linea...

متن کاملDenseness for norm attaining operator-valued functions
In this note we offer a short, constructive proof for Hilbert spaces of Lindenstrauss’ famous result on the denseness of norm attaining operators. Specifically, we show given any A ∈ L(H) there is a sequence of rank-1 operators Kn such that A+Kn is norm attaining for each n and Kn converges in norm to zero. We then apply our construction to establish denseness results for norm attaining operato...
متن کاملLipschitz Maps on Trees
We introduce and study a metric notion for trees and relate it to a conjecture of Shelah [10] about the existence of a finite basis for a class of linear orderings.
