Intersection of plane boundaries of a polytope with acute angles
E. M. Andreev M. V. Lomonosov Moscow State University
Abstract:
It is proved that the planes of nonadjacent faces of a polytope with angles not exceeding $90^\circ$ cannot intersect. It is also proved that the dimension of the intersection of any set of hyperplanes is equal to the maximum dimension of a boundary lying in this intersection.
