  • Abstract
    We introduce the notion of generalized L-upper and generalized L-lower approximation spaces under a family of information systems. We define image-upper and image-lower quasi-approximation operators in fuzzy rough sets and image-fuzzy quasi-uniform spaces as a view point of the entourage approach in a strictly two-sided, commutative (bi)-quantale. We investigate the relations between image-quasi-approximation spaces and image-fuzzy quasi-uniform spaces.
