Abstract: | The aim of this paper is to study abundant semigroups whose idempotents satisfy permutation identities. After some properties are obtained, the quasi-spined product structure of such semigroups is established while some special cases are investigated. In particular, the structure ofPI-abundant semigroups is obtained. |
