Triangular Normed Fuzzy Subalgebras in Lattice Implication Algebras

摘要

Using a t-norm T, the direct product and T-product of T-fuzzy subalgebras in lattice implication algebras are discussed, and their properties are investigated; and the notion of T-fuzzy quasi subalgebras in lattice implication algebras is introduced, and then some of Foster's results on lattice implication homomorphic image and inverse image are applied to T-fuzzy topological quasi subalgebras.
