  1. 1. Tropical aspects of real polynomials and hypergeometric functions

    University dissertation from Stockholm : Department of Mathematics

    Author : Jens Forsgård; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amoeba; Tropical Geometry; Hypergeometric function; Geometry of zeros; Discriminant; matematik; Mathematics;

    Abstract : The present thesis has three main topics: geometry of coamoebas, hypergeometric functions, and geometry of zeros.First, we study the coamoeba of a Laurent polynomial f in n complex variables. We define a simpler object, which we call the lopsided coamoeba, and associate to the lopsided coamoeba an order map. READ MORE

  2. 2. Convexity, Currents, and Lelong numbers

    University dissertation from Göteborg : Chalmers University of Technology
