Abstract

Based on the notion of \$Q\$-sup-lattices (a fuzzy counterpart of complete join-semilattices valuated in a commutative quantale), we present the concept of \$Q\$-sup-algebras -- \$Q\$-sup-lattices endowed with a collection of finitary operations compatible with the fuzzy joins. Similarly to the crisp case investigated in \cite{zhang-laan}, we characterize their subalgebras and quotients, and following \cite{solovyov-qa}, we show that the category of \$Q\$-sup-algebras is isomorphic to a certain subcategory of a category of \$Q\$-modules.
