Heap-abstraction for an object-oriented calculus with thread classes. (English) Zbl 1145.68380
Beckmann, Arnold (ed.) et al., Logical approaches to computational barriers. Second conference on computability in Europe, CiE 2006, Swansea, UK, June 30–July 5, 2006. Proceedings. Berlin: Springer (ISBN 3-540-35466-2/pbk). Lecture Notes in Computer Science 3988, 1-10 (2006).
Summary: This paper formalizes an open semantics for a calculus featuring thread classes, where the environment, consisting in particular of an overapproximation of the heap topology, is abstractly represented.
We extend our prior work not only by adding thread classes, but also in that thread names may be communicated, which means that the semantics needs to account explicitly for the possible acquaintance of objects with threads. We show soundness of the abstraction.
