PedroniVague Weak Li - Ideals and Normal Vague Li - Ideals of Lattice Implication Algebras

In this paper, we introduce the notions of vague weak LI - ideals and normal vague LI - ideals of lattice implication algebras. We discuss some properties of vague weak LI - ideals and normal vague LI - ideals. We prove that every VLI - ideal extended to normal vague LI - ideal. We study the relations between vague weak LI - ideals and VLI - ideals, vague weak LI - ideals and VILI - ideals, vague weak LI - ideals and vague weak filters, normal vague LI - ideals and vague maximal LI - ideals.
