Foldable triangulations of lattice polygons

Michael Joswig and Günter M. Ziegler

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".
