Foldable Triangulations of Lattice Polygons
arXiv:1207.6865 · doi:10.4169/amermathmont.121.08.706
Abstract
We give a simple formula for the signature of a foldable triangulation of a lattice polygon in terms of its boundary. This yields lower bounds on the number of real roots of certain of systems of polynomial equations known as "Wronski systems".
