Formal concept analysis on fuzzy sets

Formal Concept Analysis (FCA) is a theory on relations between sets, and has already been extended to a theory on fuzzy relations between (crisp) sets. In this note, in the case that (L; &) is a commutative and divisible complete residuated lattice, FCA is extended further to a theory on fuzzy relations between fuzzy sets. In particular, the fundamental theorem of FCA on fuzzy relations between fuzzy sets is established.
