摘      要：A semigroup S with a sub-band B is called a good B-quasi-Ehresmann semigroup if it is a Bsemiabundant semigroup satisfying the congruence condition such that B((ab)+)abB((ab)*)aB(a*)B(b+)b for all a,b ∈*** show that every good B-quasi-Ehresmann semigroup has a global representation and a standard *** a special case,the structure of good quasi-adequate semigroups is described.
