In the context of timed discrete-event systems, processes are allowed to realize functions that are not order-preserving with respect to the prefix ordering relation on the communicated sequences of values. This property renders naive applications of traditional domain-theoretic models inadequate for the semantic interpretation of such systems. Yet interesting results have been obtained by imposing a fixed lower bound on the reaction time of the involved processes, effectively precluding Zeno behavior [1, 2].
This work focuses on relaxing this requirement to obtain semantic interpretations even in the presence of Zeno conditions. The underlying aim is to establish a canonical denotational definition of timed discrete-event programming languages, thereby providing the means for reasoning about the correctness of the individual implementations, as well as allowing hidden commonalities of seemingly different timed systems to emerge.
