New $I^¼$ -Zariski pairs of surface singularities

Christophe Eyral, Masaharu Ishikawa, Mutsuo Oka +1

To the best of the authors' knowledge, all previously known examples of $I^¼$ -, $I^¼^{*}$ -, link-, or ordinary Zariski pairs of surface singularities in $C^{3}$ consist of (poss…

Newton weighted-LÃª-Yomdin polynomials and $I^¼$ -Zariski pairs of surface singularities

Christophe Eyral, Masaharu Ishikawa, Mutsuo Oka

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