Abstract

In analogy to the situation for continuous lattices which were introduced by Dana Scott as precisely the injective T0_0 spaces via the (nowadays called) Scott topology, we study those metric spaces which correspond to injective T0_0 approach spaces and characterise them as precisely the continuous lattices equipped with an unitary and associative [0,][0,\infty]-action. This result is achieved by a thorough analysis of the notion of cocompleteness for approach spaces.
