Junying Guo, Xiaojiang Guo · AKCE International Journal of Graphs and Combinatorics · 2025
The aim of this paper is to study the power graph of a semigroup. We obtain sufficient and necessary conditions for the independence number of the power graph of an (IC) abundant semigroups (superabundant semigroups) to be finite.
