BALANCED TRIANGULATIONS OF LATTICE POLYTOPES

By Michael Joswig and Nikolaus Witte

Abstract

Regular triangulations of products of lattice polytopes are constructed with the additional property that the dual graphs of the triangulations are bipartite. Special attention is paid to the cube case. Such triangulations are instrumental in deriving lower bounds for the number of real roots of certain sparse polynomial systems by recent results of Soprunova and Sottile [21]
