L-fuzzy covering relation
We investigate lattice-valued (L-fuzzy) covering, or fuzzy neighboring relation arising from a given lattice-valued order. We show that every L-fuzzy covering is obtained by synthesis of crisp coverings arising from the corresponding cut orderings. As a converse, we introduce and investigate lattice-valued relations, which turn out to be fuzzy coverings of fuzzy orders. (C) 2007 Elsevier B.V. All rights reserved.
