Xiaoling Li · 2006
The completely semisimple congruences on a regular biordered set are investigated,some equivalent characterization of completely semisimple congruences are obtained.Let≤ be the natural partial order on a regular semigroup.We prove that is the least completely semisimple semigroup congruence on a regular biordered set.
