that every vertex is an element of the integer lattice and each simplex of the triangulation lies in a cube of size one …. With respect to this triangulation we assume that the function satisfies some property that replaces continuity. Under this … property and some boundary condition the function has a zero point. To prove this we use a simplicial algorithm that terminates …
