# Foldable triangulations of lattice Polygons

## Michael Joswig, Günter M. Ziegler – 2012

Focus Area 1: High-complexity Geometry 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".
