Some Contributions to Perfect wrpp Semigroups 1
Feng Li, Xiaojiang Guo · 2010
The aim of this paper is to study a class of wrpp semigroups, namely, perfect wrpp semigroups. We obtain some characterization theorems of such semigroups. In particular, the spined product structure of perfect wrpp semigroups is estabilished. Also, we prove that a perfect wrpp semigroup is a strong semilattice of R-left cancellative planks.
