Abstract
In this paper, we first introduce the concept of Cayley graphs over Green \(^*\) relations of abundant semigroups by using Green \(^*\) relations. After obtaining some basic properties, we get some conditions for Cayley graphs over Green \(^*\) relations of abundant semigroups to be transmissible. Finally, we give necessary and sufficient conditions for a Cayley graph over Green \(^*\) relations of an abundant semigroup to be linear and complete, respectively.
