On Lipschitz Geometry at infinity of complex analytic sets

JE Sampaio - Calculus of Variations and Partial Differential …, 2023 - Springer
In this article, we study the Lipschitz Geometry at infinity of complex analytic sets and we
obtain results on algebraicity of analytic sets and on Bernstein's problem. Moser's Bernstein …

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 …

Bi-Lipschitz equivalent cones with different degrees

A Fernandes, Z Jelonek, JE Sampaio - arXiv preprint arXiv:2309.07078, 2023 - arxiv.org
We show that for every $ k\ge 3$ there exist complex algebraic cones of dimension $ k $
with isolated singularities, which are bi-Lipschitz and semi-algebraically equivalent but they …

Multiplicity, regularity and Lipschitz Geometry of real analytic hypersurfaces

JE Sampaio - Israel Journal of Mathematics, 2021 - Springer
This paper is devoted to studying the Lipschitz geometry of real analytic sets. We prove that
the relative multiplicities are bi-Lipschitz invariant, Lipschitz regular analytic curves are C 1 …

Local vs. global Lipschitz geometry

JE Sampaio - arXiv preprint arXiv:2305.11830, 2023 - arxiv.org
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 …

Classification of complex algebraic curves under blow-spherical equivalence

JE Sampaio, EC da Silva - Revista Matemática Complutense, 2024 - Springer
This article is devoted to studying complex algebraic sets under (global) blow-spherical
equivalence. This equivalence lives strictly between semialgebraic bi-Lipschitz equivalence …

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 …

Some results on Mattei's Conjecture

LM Câmara, F Reis, JE Sampaio - arXiv preprint arXiv:2407.09306, 2024 - arxiv.org
In this note, we present some results on the Mattei's conjecture, which asserts that the
algebraic multiplicity of one-dimensional holomorphic foliations is a topological invariant …

[PDF][PDF] ON THE TOPOLOGICAL INVARIANCE OF THE ALGEBRAIC MULTIPLICITY OF HOLOMORPHIC FOLIATIONS

LM CÂMARA, F REIS, JE SAMPAIO - researchgate.net
In this paper, we address one of the most basic and fundamental problems in the theory of
foliations and ODEs, the topological invariance of the algebraic multiplicity of a holomorphic …
