Composing Invariants

Composing Invariants

Download www.cs.unh.edu

We explore the question of the composition of invariance speciﬁcations in a context of concurrent and reactive systems. Depending on how compositionality is stated and how invariants are deﬁned, invariance speciﬁcations may or may not be compositional. This article ﬁrst examines two classic forms of invariants and their compositional properties. After pointing out what we see as deﬁciencies of these two kinds of invariants, two new forms are deﬁned and shown to have useful compositional properties that the more classic forms do not enjoy. The last form, in particular, is shown to be well suited to situations where none of the other three is adapted. c 2005 Elsevier B.V. All rights reserved.
