neutrosophic n-structures on sheffer stroke be-algebras

In this study, a neutrosophic $mathcal{n}$subalgebra, a (implicative) neutrosophic $mathcal{n}$ filter, level sets of these neutrosophic $mathcal{n}$structures and their properties are introduced on a sheffer stroke bealgebras (briefly, sbealgebras). it is proved that the level set of neutrosophic $mathcal{n}$ subalgebras ((implicative) neutrosophic $mathcal{n}$filter) of this algebra is the sbesubalgebra ((implicative) sbefilter) and vice versa. then we present relationships between upper sets and neutrosophic $mathcal{n}$filters of this algebra. also, it is given that every neutrosophic $mathcal{n}$filter of a sbealgebra is its neutrosophic $mathcal{n}$subalgebra but the inverse is generally not true. we study on neutrosophic $mathcal{n}$filters of sbealgebras by means of sbehomomorphisms, and present relationships between mentioned structures on a sbealgebra in detail. finally, certain subsets of a sbealgebra are determined by means of $mathcal{n}$functions and some properties are examined.
