Computation Tree Logic with Deadlock Detection

Rob van Glabbeek ; Bas Luttik ; Nikola Trcka.

We study the equivalence relation on states of labelled transition systems of satisfying the same formulas in Computation Tree Logic without the next state modality (CTL-X). This relation is obtained by De Nicola & Vaandrager by translating labelled transition systems to Kripke structures, while&nbsp;[&hellip;]

Equivalence checking for weak bi-Kleene algebra

Tobias Kappé ; Paul Brunet ; Bas Luttik ; Alexandra Silva ; Fabio Zanasi.

Pomset automata are an operational model of weak bi-Kleene algebra, which describes programs that can fork an execution into parallel threads, upon completion of which execution can join to resume as a single thread. We characterize a fragment of pomset automata that admits a decision procedure for&nbsp;[&hellip;]

The $\pi$-Calculus is Behaviourally Complete and Orbit-Finitely Executable

Bas Luttik ; Fei Yang.

Reactive Turing machines extend classical Turing machines with a facility to model observable interactive behaviour. We call a behaviour (finitely) executable if, and only if, it is equivalent to the behaviour of a (finite) reactive Turing machine. In this paper, we study the relationship between&nbsp;[&hellip;]

Pushdown Automata and Context-Free Grammars in Bisimulation Semantics

Jos C. M. Baeten ; Cesare Carissimo ; Bas Luttik.

The Turing machine models an old-fashioned computer, that does not interact with the user or with other computers, and only does batch processing. Therefore, we came up with a Reactive Turing Machine that does not have these shortcomings. In the Reactive Turing Machine, transitions have labels to&nbsp;[&hellip;]
