Temporal Antecedent Failure: Refining Vacuity
We re-examine vacuity in temporal logic model checking. We note two disturbing phenomena in recent results in this area. The first indicates that not all vacuities detected in prac...

Checking Coverage for Infinite Collections of Timed Scenarios
We consider message sequence charts enriched with timing constraints between pairs of events. As in the untimed setting, an infinite family of time-constrained message sequence cha...

Decidability Results for Well-Structured Transition Systems with Auxiliary Storage
Abstract. We consider the problem of verifying the safety of wellstructured transition systems (WSTS) with auxiliary storage. WSTSs with storage are automata that have (possibly) i...

Equivalence Checking for Infinite Systems Using Parameterized Boolean Equation Systems
Abstract. In this paper, we provide a transformation from the branching bisimulation problem for infinite, concurrent, data-intensive systems in linear process format, into solving...

On Modal Refinement and Consistency
Abstract. Almost 20 years after the original conception, we revisit several fundamental questions about modal transition systems. First, we demonstrate the incompleteness of the st...

Is Observational Congruence Axiomatisable in Equational Horn Logic?
It is well known that bisimulation on µ-expressions cannot be finitely axiomatised in equational logic. Complete axiomatisations such as those of Milner and Bloom/´Esik necessar...

Asynchronous Games: Innocence Without Alternation
The notion of innocent strategy was introduced by Hyland and Ong in order to capture the interactive behaviour of λ-terms and PCF programs. An innocent strategy is defined as an ...

Precise Fixpoint-Based Analysis of Programs with Thread-Creation and Procedures
We present a fixpoint-based algorithm for context-sensitive interprocedural kill/gen-analysis of programs with thread creation. Our algorithm is precise up to abstraction of sync...
