Abstract |
When some hyperplanes H_1, ..., H_m of the n-dimensional Euclidean space R^n are given in general position, Schläfli has determined the number of the bounded connected components in R^n - ∪^m_i = _1H_i, the complementary set of the union of the hyperplanes. It is equal to the binomial coefficient ((m-1)/n), which is also equal to the number of vertices which are the intersections of n hyperplanes in H_1, ..., H_<m-1>. Although Schläfli's proof is implicit and intuitive, the fact reflects an interesting aspect concerning configurations of hyperplanes. We clarify how the condition of general position works, and re-prove the fact in all of its details.
