Milnor open books and Milnor fillable contact 3-manifolds
C. Caubel, A. Nemethi, P. Popescu-Pampu
We say that a contact manifold is Milnor fillable if it is contactomorphic to the contact boundary of an isolated complex-analytic singularity (X,x). Generalizing results of Milnor…

On the analytical invariance of the semigroups of a quasi-ordinary hypersurface singularity
Patrick Popescu-Pampu
We associate to any irreducible germ S of complex quasi-ordinary hypersurface an analytically invariant semigroup. We deduce a direct proof (without passing through their embedded…
