Domaine d'influence (Fr). Wirkungsbereich (Ge). Dominio di influenza (It)

The domain of influence of a lattice point P (Delaunay 1933), or Dirichlet domain or Voronoi domain, consists of all points Q in space that are closer to this lattice point than to any other lattice point or at most equidistant to it, namely such that OP ≤|t - OP| for a any vector t belonging to the vector lattice L. It is the inside of the Wigner-Seitz cell.
