1. 1. On Hypersurface Coamoebas and Integral Representations of A-Hypergeometric Functions

   Författare :Jens Forsgård; Boris Shapiro; Elizabeth Wulcan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; matematik; Mathematics;

   Sammanfattning : This thesis is concerned with coamoebas and their connection to integral representations A-hypergeometric functions. In the first part, we introduce the lopsidedness criterion for coamoebas, and define the lopsided coamoeba. We show that the lopsided coamoeba comes naturally equipped with an order map. LÄS MER

3. 2. Tropical aspects of real polynomials and hypergeometric functions

   Sammanfattning : 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. LÄS MER
