Basic Theory of Reduction Congruence for Two Timed Asynchronous π-Calculi

摘要

We study reduction congruence, the most widely used notion of equality for the asynchronous π-calculus with timers, and derive several alternative characterisations, one of them being a labelled asynchronous bisimilarity. These results are adapted to an asynchronous π-calculus with timers, locations and message failure. In addition we investigate the problem of how to distribute value-passing processes in a semantics-preserving way.
