On the link of Lipschitz normally embedded sets

R Mendes, JE Sampaio - International Mathematics Research …, 2024 - academic.oup.com
A path-connected subanalytic subset in is naturally equipped with two metrics: the inner and
the outer metrics. We say that a subset is Lipschitz normally embedded (LNE) if these two …

Characterization of Lipschitz normally embedded complex curves and Lipschitz trivial values of polynomial mappings

ALA Costa - 2023 - repositorio.ufc.br
We study Lipschitz geometry of fibers of complex polynomial mappings from two points of
view: the equivalence of inner and outer metrics of an algebraic curve and the existence of a …

On Lipschitz normally embedded singularities

L Fantini, A Pichon - Handbook of Geometry and Topology of Singularities …, 2023 - Springer
Abstract Any subanalytic germ (X, 0)⊂(ℝ n, 0) is equipped with two natural metrics: its outer
metric, induced by the standard Euclidean metric of the ambient space, and its inner metric …

Universality theorem for LNE H\" older triangles

L Birbrair, M Denkowski, DL Medeiros… - arXiv preprint arXiv …, 2024 - arxiv.org
We compare ambient and outer Lipschitz geometry of Lipschitz normally embedded H\"
older triangles in $\mathbb {R}^ 4$. In contrast to the case of $\mathbb {R}^ 3$ there are …

Outer Lipschitz Classification of Normal Pairs of H\" older Triangles

L Birbrair, A Gabrielov - arXiv preprint arXiv:2311.09461, 2023 - arxiv.org
A normal pair of H\" older triangles is the union of two normally embedded H\" older triangles
satisfying some natural conditions on the tangency orders of their boundary arcs. It is a …

Lipschitz geometry and combinatorics of abnormal surface germs

A Gabrielov, E Souza - Selecta Mathematica, 2022 - Springer
We study outer Lipschitz geometry of real semialgebraic or, more general, definable in a
polynomially bounded o-minimal structure over the reals, surface germs. In particular, any …

A characterization of Lipschitz normally embedded surface singularities

WD Neumann, HM Pedersen… - Journal of the London …, 2020 - Wiley Online Library
Any germ of a complex analytic space is equipped with two natural metrics: the outer metric
induced by the hermitian metric of the ambient space and the inner metric, which is the …

Local versus global Lipschitz geometry

JE Sampaio - Journal of the London Mathematical Society, 2024 - Wiley Online Library
In this article, we prove that for a definable set in an o‐minimal structure with connected link
(at 0 or infinity), the inner distance of the link is equivalent to the inner distance of the set …

On a link criterion for Lipschitz normal embeddings among definable sets

NXV Nhan - Mathematische Nachrichten, 2023 - Wiley Online Library
It is known by a result of Mendes and Sampaio that the Lipschitz normal embedding of a
subanalytic germ is fully characterized by the Lipschitz normal embedding of its link. In this …

Metrically Un-knotted Corank 1 Singularities of Surfaces in

L Birbrair, R Mendes, JJ Nuño-Ballesteros - The Journal of Geometric …, 2018 - Springer
The paper is devoted to relations between topological and metric properties of germs of real
surfaces, obtained by analytic maps from R^ 2 R 2 to R^ 4. R 4. We show that for a big class …
