right normal element

By using ρ T,we establish a representation for a right regular band.

借助 ρT 建立右正则带的一种表

Shevrin posed an open problem in Reference[1]: are semigroups whose lattice of subsemigroups is complemental periodic? In this paper, it is proved that the openproblem has positive answers for inverse semigroups, rectangular groups and E-right(left) unitary regular semigroups with left(right) normal band.
