Abstract In [R. Heckmann, K. Keimel, Quasicontinuous Domains and the Smyth Powerdomain, Electronic Notes in Theoretical Computer Science 298 (2013), 215–232], Heckmann and Keimel proved that a dcpo P is quasicontinuous iff the poset Fin P of nonempty finitely generated upper sets ordered by reverse inclusion is continuous. We generalize this result to general topological spaces in this paper. More precisely, for any T 0 space (X, τ) and U∈ τ, we construct a topology τ F generated by the basic open subsets U F={↑ F∈ Fin X: F⊆ U}. It is shown that a T 0 space (X, τ) is a hypercontinuous lattice iff τ F is a completely distributive lattice. In particular, we prove that if a poset P satisfies property DINT op, then P is quasi-hypercontinuous iff Fin P is hypercontinuous.
