Triangulation de Delaunay et Triangulation des Tores

摘要

We present a construction of triangulations of the torus mathbbTn{mathbb{T}^n} with 2 n+1−1 vertices, starting from the Delaunay triangulation of a generic lattices. The typical example is the Kühnel–Lassmann triangulation, with help of the lattice A*_n{A^{*}_{n}} . Concerning this triangulation, we also prove a result of unicity for some values of n.
