Motivic Milnor fiber of a quasi-ordinary hypersurface

Abstract

Let $f$ be a germ of complex analytic function at $({\mathbf{C}}^{d+1},0)$ such that its zero level defines an irreducible germ of quasi-ordinary hypersurface $(S,0)$. We describe the motivic Igusa zeta function, the motivic Milnor fibre and the Hodge-Steenbrink spectrum of $f$ at 0 in terms of topological invariants of the quasi-ordinary hypersurface $(S,0)$.
