Abstract
We study the regular matrices in the semigroup H(n) of Hall matrices ( Boolean matrices with positive permanent). We study some necessary and sufficient conditions for a Hall matrix to be regular in H(n) in term s of idempotent matrices, adjoint matrices, and identifying permutatio n matrices.
