Abstract: We introduce the concepts of Alexandrov L-fuzzy pre-uniformities in complete residuated lattices. We obtain Alexandrov L-fuzzy topologies, L-lower approximation operators and L-upper approximation operators induced by Alexandrov L-fuzzy pre-uniformities. Conversely, we obtain Alexandrov L-fuzzy pre-uniformities induced by L-lower approximation operators and L-upper approximation operators.

Keywords: Complete residuated lattices, Alexandrov L-fuzzy topologies, L-lower and L-upper approximation operators, Alexandrov L-fuzzy pre-uniformities
