Images and preimages of L-filterbases
We introduce the notion of L-filterbase on a strictly two-sided, commutative quantale lattice L. We define two types of the images and preimages of L-filterbases using Zadeh image and preimage operators. We study the images and preimages of L-filterbases induced by functions. We investigate their properties. (C) 2006 Elsevier B.V. All rights reserved.
