    • 2016, Jens Forsgård, “Coamoebas of polynomials supported on circuits”, in arXiv[1]:
      Our results include an explicit description of the space of coamoebas, a relation between connected components of the coamoeba complement and critical points of the polynomial, an upper bound on the area of a planar coamoeba, and a recovered bound on the number of positive solutions of a fewnomial system..
