Abstract

We introduce the concept of a -closed set and a -homomorphism in lattice implication algebras, and we discuss some of their properties. Next, we introduce the fuzzy implicative filter and obtain equivalent conditions. Finally, we discuss the operation , fuzzy filters and fuzzy implicative filters.
