Completely regular and orthodox congruences on regular semigroups
1993Let \(\rho\) be a congruence relation on a regular semigroup \(S\). Define \(\rho^ K\) [resp. \(\rho^ V\)] to be the greatest congruence relation on \(S\) such that the idempotent \((\rho^ K /\rho)\)-classes [resp. \((\rho^ V/ \rho)\)-classes] are bands [resp. rectangular bands].
