On Cayley graphs of completely 0-simple semigroups
Shoufeng Wang, Yinghui Li · Open Mathematics · 2012
Abstract We give necessary and sufficient conditions for various vertex-transitivity of Cayley graphs of the class of completely 0-simple semigroups and its several subclasses. Moreover, the question when the Cayley graphs of completely 0-simple semigroups are undirected is considered.
