(L,⊙)(L,⊙)-approximation spaces and (L,⊙)(L,⊙)-fuzzy quasi-uniform spaces

We introduce the notion of generalized L-upper and generalized L  -lower approximation spaces under a family of information systems. We define (L,⊕)(L,⊕)-upper and (L,⊙)(L,⊙)-lower quasi-approximation operators in fuzzy rough sets and (L,⊙)(L,⊙)-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 (L,⊙,⊕)(L,⊙,⊕)-quasi-approximation spaces and (L,⊙)(L,⊙)-fuzzy quasi-uniform spaces.
