Abstract
We give a new proof of Ryser's conjecture asserting that in the class of $t h X t h$ (0, 1)-matrices with row sums and column sums equal to $t$ the permanent function takes its maximum on the direct sum of $t X t$ matrices of l'$s$.
Moreover we give a counterexample to a Brualdi's conjecture.
