Separability in the Ambient Logic
Abstract. The Ambient Logic (AL) has been proposed for expressing properties of process mobility in the calculus of Mobile Ambients (MA), and as a basis for query languages on semistructured data. We study some basic questions concerning the discriminating power of AL, focusing on the equivalence on processes induced by the logic (=L). As underlying calculi besides MA we consider a subcalculus in which an image-finiteness condition holds and that we prove to be Turing complete. Synchronous variants of these calculi are studied as well. In these calculi, we provide two operational characterisations of =L: a coinductive one (as a form of bisimilarity) and an inductive one (based on structual properties of processes). After showing =L to be stricly finer than barbed congruence, we establish axiomatisations of =L on the subcalculus of MA (both the asynchronous and the synchronous version), enabling us to relate =L to structural congruence. We also present some (un)decidability results that...
