Quasi-ordinary surface germs from the topological viewpoint
Françoise Michel, Claude Weber
In the article we give a self-contained new proof that a normal quasi-ordinary surface germ is analytically isomorphic to a cyclic quotient surface germ.
On the Visibility of Alternating +Achiral Knots
Nicola Ermotti, Cam Van Quach Hongler, Claude Weber
This article is devoted to the study of prime alternating +achiral knots. In the case of arborescent knots, we prove in +AAA Visibility Theorem 5.1, that the symmetry is visible on…
Michel Kervaire work on knots in higher dimensions
Francoise Michel, Claude Weber
We present Michel Kervaire work on knots in higher dimensions.
On the Kawauchi conjecture about the Conway polynomial of achiral knots
Nicola Ermotti, Cam Van Quach Hongler, Claude Weber
We give a counterexample to the Kawauchi conjecture on the Conway polynomial of achiral knots which asserts that the Conway polynomial of an achiral knot satisfies the split…
Malnormal subgroups and Frobenius groups: basics and examples
Pierre de la Harpe, Claude Weber, Appendix by Denis Osin
Malnormal subgroups occur in various contexts. We review a large number of examples, and we compare the situation in this generality to that of finite Frobenius groups of permutati…
On malnormal peripheral subgroups in fundamental groups of 3-manifolds
Pierre de la Harpe, Claude Weber
Let be a non-trivial knot in the 3-sphere, its exterior, its group, and its peripheral subgroup. We show that …
