Abd El‐Mohsen Badawy · Journal of the Egyptian Mathematical Society · 2015
In this paper the notion of d L -filters is introduced and characterized in principal MS -algebras. Also many properties of principal d L -filters of a principal MS -algebra are observed and a characterization of the class of all principal d L -filters is given. Finally, a relationship between d L -filters and congruences on a principal MS -algebra is investigated.
