Abstract:

The main purpose of this paper is to show that a regular semigroup $S$ is a semilattice of bisimple semigroups if and only if it is a band of bisimple semigroups and that this holds if and only if $\mathcal {D}$ is a congruence on $S$. It is also shown that a quasiregular semigroup $S$ which is a rectangular band of bisimple semigroups is itself bisimple.
