Counting on rectangular areas

Combinatorics 2007-05-23 v1

Abstract

In the first section of this paper we prove a theorem for the number of columns of a rectangular area that are identical to the given one. In the next section we apply this theorem to derive several combinatorial identities by counting specified subsets of a finite set.
