LR-normal orthogroup congruence on regular semigroups
Xing Jian-min · Journal of Shandong University · 2006
The LR-normal orthogroup congruences on a regular semigroups in terms of their LR-normal orthogroup congruence pairs are described.In particular,there is a bijection between the set of all LR-normal orthogroup congruence pairs of S and the set of all LR-normal orthogroup congruences on S.
