Abstract
For a quantale \(\mathsf{V}\), first a closure-theoretic approach to completeness and separation in \(\mathsf{V}\text{-categories}\) is presented. This approach is then generalized to , where is a topological theory that entails a set monad \( \mathbb{T}\) and a compatible \( \mathbb{T}\text{-algebra}\) structure on \(\mathsf{V}\).
