L-fuzzy Scott Topology and Scott Convergence of Stratified L-filters on Fuzzy Dcpos

On a fuzzy dcpo with a frame L as its valued lattice, we define an L-fuzzy Scott topology by means of graded convergence of stratified L-filters. It is a fuzzy counterpart of the classical Scott topology on a crisp dcpo. The properties of L-fuzzy Scott topology are investigated. We establish Scott convergence theory of stratified L-filters. We show that for an L-set, its degree of Scott openness equals to the degree of Scott continuity from the underlying fuzzy dcpo to the lattice L (also being viewed as a fuzzy poset). We also show that a fuzzy dcpo is continuous iff for any stratified L-filter, Scott convergence coincides with topological convergence (w.r.t. the L-fuzzy Scott topology)
