Some Properties of Subsets in Lattice Implication Algebra
Long Xi-qing · Journal of Yibin University · 2010
Some properties of subsets were studied in the lattice implication algebra.The property of subsets in the direct product of lattice implication algebras was focused on and the proposition that(B1× B2)(α)=B1(α1)× B2(α2) while that B1×B2 was the subset of L1× L2 was proved.
