SPECIAL SEMIGROUP AMALGAMS OF QUASI UNITARY SUBSEMIGROUPS AND OF QUASI NORMAL BANDS
Noor Alam, Noor Mohammad Khan · Asian-European Journal of Mathematics · 2013
We show that the special semigroup amalgam with core as a quasi-unitary subsemigroup is embedded in a semigroup. We also show that the special semigroup amalgam within the class of left [right] quasinormal bands is embeddable in a left [right] quasinormal band.
