Abstract

Let SS be a Puiseux series of the germ of an analytically irreducible plane curve ZZ. We provide a new perspective to construct a set of polynomials F={F1,,Fg1}F=\{F_1,\ldots, F_{g-1}\} associated to SS, which is a special choice of maximal contact elements constructed in [AMB17] and approximate roots defined in [Dur18], [AM73a], [AM73b]. Using these polynomials as building blocks, we describe a set of generators of multiplier ideals of the form I(αZ)\mathfrak{I}(\alpha Z) with 0<α<10<\alpha<1 a rational number, which recovers the results about irreducible plane curves in [AMB17], [Dur18].
