With the unit interval [0,1] as the truth value table, Chen and Wu
presented the concept of  possibility computation over dcpos.
Indeed, every possibility computation can be considered as a
[0,1]-valued Scott open set on a dcpo. The aim of this paper is to
study Chen-Wu's duality on quantale-valued setting. For clarity,
with a commutative unital quantale $L$ as the truth value table, we
introduce a concept of fuzzy possibility computations over fuzzy
dcpos and then establish an equivalence between their denotational
semantics and their logical semantics.
