The Strong Semilattice of Pi-groups
Jiangang Zhang, Yuhui Yang, Ran Shen · European Journal of Pure and Applied Mathematics · 2018
A semigroup is called a GV-inverse semigroup if and only if it is isomorphic to a semilattice of $\pi$-groups. In this paper, we give the sufficient and necessary conditions for a GV-inverse semigroup to be a strong semilattice of $\pi$-groups. Some conclusions about Clifford semigroups are generalized.
