On a class of binary matrices
by
Krassimir Iordjev
South-West University, Blagoevgrad

The set \Lambdank of all n ×n matrices with k identities in every row and every column is discussed. Fixing an entry, let \pink and \nunk be the numbers of all matrices in \Lambdank with respectively 1 and 0 in this entry. The relation between \pink and \nunk is found. Some applications of this relation are given.
