On Milnor's fibration theorem and its offspring after 50 years

J Seade - Bulletin of the American Mathematical Society, 2019 - ams.org
Milnor's fibration theorem is about the geometry and topology of real and complex analytic
maps near their critical points, a ubiquitous theme in mathematics. As such, after 50 years …

Lipschitz geometry of complex curves

WD Neumann, A Pichon - arXiv preprint arXiv:1302.1138, 2013 - arxiv.org
We describe the Lipschitz geometry of complex curves. For the most part this is well known
material, but we give a stronger version even of known results. In particular, we give a quick …

Lipschitz normal embeddings in the space of matrices

D Kerner, HM Pedersen, MAS Ruas - Mathematische Zeitschrift, 2018 - Springer
A semi-algebraic subset in R^ n R n or C^ n C n is naturally equipped with two different
metrics, the inner metric and the outer metric. Such a set (or its germ) is called Lipschitz …

Lipschitz geometry of complex surfaces: analytic invariants and equisingularity

WD Neumann, A Pichon - arXiv preprint arXiv:1211.4897, 2012 - arxiv.org
We prove that the outer Lipschitz geometry of a germ $(X, 0) $ of a normal complex surface
singularity determines a large amount of its analytic structure. In particular, it follows that any …

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 …

Tangent cones of Lipschitz normally embedded sets are Lipschitz normally embedded. Appendix by Anne Pichon and Walter D. Neumann

A Fernandes, JE Sampaio - … Mathematics Research Notices, 2019 - academic.oup.com
We prove that tangent cones of Lipschitz normally embedded sets are Lipschitz normally
embedded. We also extend to real subanalytic sets the notion of reduced tangent cone and …

Multiplicity, regularity and blow-spherical equivalence of complex analytic sets

JE Sampaio - arXiv preprint arXiv:1702.06213, 2017 - arxiv.org
This paper is devoted to study multiplicity and regularity as well as to present some
classifications of complex analytic sets. We present an equivalence for complex analytical …

Regular vectors and bi-Lipschitz trivial stratifications in o-minimal structures

G Valette - Handbook of Geometry and Topology of Singularities …, 2023 - Springer
These notes deal with semialgebraic and subanalytic subsets of ℝ n, and more generally
with all the sets that are definable in a polynomially bounded o-minimal structure expanding …

Fast vanishing cycles on perturbations of (complex) weighted-homogeneous germs

D Kerner, R Mendes - arXiv preprint arXiv:2311.13423, 2023 - arxiv.org
Let X_o be a complex weighted-homogeneous complete intersection germ,(possibly non-
reduced). Let X be a perturbation of X_o by``higher-order-terms". We give sufficient criteria …

Thick-thin decomposition for real definable isolated singularities

L Birbrair, A Fernandes, V Grandjean - Indiana University Mathematics …, 2017 - JSTOR
Two subset germs of Euclidean spaces are called blow-spherically equivalent if their
spherical modifications are homeomorphic and the homeomorphism induces …
