Neutrosophic ℵ-ideals in semigroups

The aim of this paper is to introduce the notion of neutrosophic ℵ −ideals in semigroups
and investigate their properties. Conditions for neutrosophic ℵ −structure to be a neutrosophic
ℵ −ideal are provided. We also discuss the concept of characteristic neutrosophic ℵ −structure of
semigroups and its related properties.
