Stereographic compactification and affine bi-Lipschitz homeomorphisms
Vincent Grandjean, Roger Oliveira
Let be the inverse of the stereographic projection with centre the north pole . Let be a closed subset of $\mathbb{R}^{q…
Thin-thick decomposition for real definable isolated singularities
Lev Birbrair, Alexandre Fernandes, Vincent Grandjean
Two subset germs of Euclidean spaces are called blow-spherically equivalent, if their spherical modifications are homeomorphic and the homeomorphism induces homeomorphic tangent li…
Collapsing topology of isolated singularities
Lev Birbrair, Alexandre Fernandes, Vincent Grandjean
We proof here the existence of a topological thick and thin decomposition of any closed definable thick isolated singularity germ in the spirit of the recently discovered metric th…
Choking horns in Lipschitz Geometry of Complex Algebraic Varieties
Lev Birbrair, Alexandre Fernandes, Vincent Grandjean +1
We study the Lipschitz Geometry of Complex Algebraic Singularities. For this purpose we introduce the notion of choking horns. A Choking horn is a family of cycles on the family of…
