Multiplier ideals of analytically irreducible plane curves

Abstract

Let $S$ be a Puiseux series of the germ of an analytically irreducible plane curve $Z$. We provide a new perspective to construct a set of polynomials $F=\{F_1,\dots ,F_{g-1}\}$ associated to $S$, 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 $\mathfrak{I}(\alpha Z)$ with $0<\alpha <1$ a rational number, which recovers the results about irreducible plane curves in [AMB17], [Dur18].
