Amoeba-shaped polyhedral complex of an algebraic hypersurface

Algebraic Geometry 2017-08-24 v1

Abstract

Given a complex algebraic hypersurface~HH, we introduce a polyhedral complex which is a subset of the Newton polytope of the defining polynomial for~HH and enjoys the key topological and combinatorial properties of the amoeba of~H.H. We provide an explicit formula for this polyhedral complex in the case when the spine of the amoeba is dual to a triangulation of the Newton polytope of the defining polynomial. In particular, this yields a description of the polyhedral complex when the hypersurface is optimal.
