A note on Green’s relations on the semigroup _{}.

Solvability criteria for nonnegative matrix equations are applied in characterizing the first three of the four Green's relations C, 6 6D and i on the semigroup Nn of all n x n nonnegative matrices. For the relation i, it is shown that 6D = i when the relation is restricted to the regular matrices in
