Abstract
(English)
We introduce two observational logics for reasoning about Distributed Transition Systems (DTS). These logics characterize different classes of properties of DTS compurations. The first logic, LD, is a straightforward generalization of Hennessy-Milner Logic obtained by allowing modalities indexed by partial ordering observations; it is in full agreement with a computationally defined observational equivalence for true concurrency. The second logic, LP, has as a distinctive feature a past operator which appears to be crucial for adequately describing the interplay of concurrency and nondeterminism. A deeper understanding of Lp is gained by showing that it induces On DTS the same identification of another observational semantics.
