Abstract

Let be an matrix of zeros and ones. The matrix is said to be a Ferrers matrix if it has decreasing row sums and it is row and column dense with nonzero -entry. We characterize all linear maps perserving the set of Ferrers vectors over the binary Boolean semiring and over the Boolean ring . Also, we have achieved the number of these linear maps in each case.
