<em>L</em>-Fuzzy Rough Approximation Operators Based on Co-Implication and Their (Single) Axiomatic Characterizations

For <i>L</i> a complete co-residuated lattice and <i>R</i> an <i>L</i>-fuzzy relation, an <i>L</i>-fuzzy upper approximation operator based on co-implication adjoint with <i>L</i> is constructed and discussed. It is proved that, when <i&...
