A Ronkin type function for coamoebas

Complex Variables 2014-12-05 v1 Algebraic Geometry Combinatorics

Abstract

The Ronkin function plays a fundamental role in the theory of amoebas. We introduce an analogue of the Ronkin function in the setting of coamoebas. It turns out to be closely related to a certain toric arrangement known as the shell of the coamoeba and we use our Ronkin type function to obtain some properties of it.
