Sets of definitive prefixes are called definitive sets. Defining a semantics for LTL in terms of definitive sets gives us something equivalent to LTL3, a formulation popular in runtime verification. Our theory of definitive sets is sufficient to give a neat characterisation of (co-)safety and (co-)liveness properties, allowing us to straightforwardly prove Alpern and Schneider’s result that every property is the intersection of a safety and liveness property by simpler means.}

In a linear-time temporal setting, properties take the form of sets of behaviours (infinite sequences of states). In this talk, I will arrange the various monitorability classes found in the literature into a hierarchy along with well-known classes of properties such as safety and guarantee properties. I then give each of these monitorability classes neat topological characterisations within the topology induced by the "guarantee kernel" interior operator. Lastly, I show that the metric space used by [Alpern and Schneider](alpern-schneider-1985) coincides with our topology.}
