Disentangling mappings defined on ICIS

Alberto Fernández-Hernández, Juan J. Nuño-Ballesteros

We study germs of hypersurfaces $(Y, 0) \subset (C^{n + 1}, 0)$ that can be described as the image of $A$ -finite mappings $f : (X, S) \to (C^{n + 1}, 0)$ defin…

A note on complex plane curve singularities up to diffeomorphism and their rigidity

A. Fernández-Hernández, R. Giménez Conejero

We prove that, if two germs of plane curves $(C, 0)$ and $(C^{'}, 0)$ with at least one singular branch are equivalent by a (real) smooth diffeomorphism, then $C$ is complex isomorphic…
