Jumps of Milnor numbers of Brieskorn-Pham singularities in non-degenerate families

Tadeusz Krasiński, Justyna Walewska

The jump of the Milnor number of an isolated singularity is the minimal non-zero difference between the Milnor numbers of and one of its deformation In t…

A short proof that equisingular plane curve singularities are topologically equivalent

Szymon Brzostowski, Tadeusz Krasiński, Justyna Walewska

We prove that if two plane curve singularities are equisingular, then they are topologically equivalent. The method we will use is P.~Fortuny~Ayuso's who proved this result for irr…

Arnold's problem on monotonicity of the Newton number for surface singularities

Szymon Brzostowski, Tadeusz Krasiński, Justyna Walewska

According to the Kouchnirenko theorem, for a generic (precisely non-degenerate in the Kouchnirenko sense) isolated singularity its Milnor number is equal to the Newton n…

Milnor numbers of deformations of semi-quasi-homogeneous plane curve singularities II

Maria Michalska, Justyna Walewska

We show the possible Milnor numbers of deformations of semi-quasi-homogeneous isolated plane curve singularities. In Theorem 1.1 we list integers can be attained as Milnor numbers…

Non-degenerate jump of Milnor numbers of surface singularities

Szymon Brzostowski, Tadeusz Krasiński, Justyna Walewska

The jump of the Milnor number of an isolated singularity is the minimal non-zero difference between the Milnor numbers of and one of its deformations . We give a…

Milnor numbers of deformations of semi-quasi-homogeneous plane curve singularities

Maria Michalska, Justyna Walewska

The aim of this paper is to show the possible Milnor numbers of deformations of semi-quasi-homogeneous isolated plane curve singularities. Main result states that if is irreduc…

Milnor numbers in deformations of homogeneous singularities

Szymon Brzostowski, Tadeusz Krasinski, Justyna Walewska

Let f_0 be a plane curve singularity. We study the Minor numbers of singularities in deformations of f_0. We completely describe the set of these Milnor numbers for homogeneous sin…
