New -Zariski pairs of surface singularities

Christophe Eyral, Masaharu Ishikawa, Mutsuo Oka +1

To the best of the authors' knowledge, all previously known examples of -, -, link-, or ordinary Zariski pairs of surface singularities in consist of (possib…

Newton weighted-Lê-Yomdin polynomials and -Zariski pairs of surface singularities

Christophe Eyral, Masaharu Ishikawa, Mutsuo Oka

We investigate surface singularities defined by weighted-Lê-Yomdin polynomials, with a particular focus on a specific subclass that we refer to as Newton weighted-Lê-Yomdin polynom…

On Milnor-Orlik's theorem and admissible simultaneous good resolutions

Christophe Eyral, Mutsuo Oka

Let be a (possibly Newton degenerate) weighted homogeneous polynomial defining an isolated surface singularity at the origin of , and let be a generic d…

Blow- singularities and -constant deformations

Christophe Eyral, Mutsuo Oka

We introduce a class of complex surface singularities - the blow- singularities - which are likely to be stable with respect to -constant deformations. We prove such a st…

Zeta-function and -Zariski pairs of surfaces

Christophe Eyral, Mutsuo Oka

A Zariski pair of surfaces is a pair of complex polynomial functions in which is obtained from a classical Zariski pair of projective curves and…

On -Zariski pairs of links

Mutsuo Oka

The notion of Zariski pairs for projective curves in is known since the pioneer paper of Zariski \cite{Zariski} and for further development, we refer the reference in…
