Polyhedral Voronoi cellsIna Voigt and Stephan WeisFakultät für Mathematik, Technische Universität Dortmund, Vogelpothsweg 87, D-44227 Dortmund, Germany, E-mail: ina.voigt@tu-dortmund.de;Department Mathematik, Friedrich-Alexander-Universität Erlangen-Nürnberg, Bismarckstraße 1 1/2, D-91054 Erlangen, Germany, E-mail: weis@mi.uni-erlangen.de Abstract: Voronoi cells of a discrete set in Euclidean space are known as generalized polyhedra. We identify polyhedral cells of a discrete set through a direction cone. For an arbitrary set we distinguish polyhedral from non-polyhedral cells using inversion at a sphere and a theorem of semi-infinite linear programming. Keywords: Voronoi cell, polyhedron, discrete point set Classification (MSC2000): 52C22, 51M20 Full text of the article (for subscribers):
