We generalize Green’s ρ relations from usual semigroups into (n,m)-semigroups. We further define left congruence, quasistrong ρ-broad (n,m)-semigroups and strong ρbroad (n,m)-semigroups and address their fundamental properties.

Key words: strong ρ-broad (n,m)-semigroups, (n,m)-semigroups, left congruence, quasistrong ρbroad (n,m)-semigroups
