To quickly assess the difficulty of the text, read a short excerpt:
Conversely, by Lemma 4 each G e // is contained in the closure of some connected component S of L, and by maximahty of G it is easy to see that G coincides with a connected component of the intersection of T with the face containing G. Hence the set H is the set of all faces of connected components of L. Next let G, G' be two connected face components such that [G, G'] i Hq; let / be their common (n-2)-dimensional subface. Take an internal point p of /, and a neighborhood of p not intersecting ...any other (n-l)-faces of L. We can plainly introduce coordinates near p which make~G, G' appear locally as two coordinate half -planes, and L appear locally as the 'wedge' of Euclidean space which these half-planes bound. Note that since all half-spaces bounding the polyhedra AT, are linearly independent (as follows from Lemma 1) no other face passes through p, or else p would be a boundary point rather than an interior point of /. This makes it clear that G and G' are faces of the same connected component of L.
