ns. Finally, we study abstract properties of selection operators connected to belief set operators, which are used to choose some of the possible belief sets.
Abstract. This paper shows that the suitable orderings for proving innermost termination are characterized by the innermost parallel monotonicity, IP-monotonicity for short. This p...
Using separation logic, this paper presents three Hoare logics (corresponding to different notions of correctness) for the simple While language extended with commands for heap acc...
We present a process algebraic intruder model for verifying a class of liveness properties of security protocols. For this class, the proposed intruder model is proved to be equiv...
Abstract. We prove a conjecture by A. Pnueli and strengthen it showing a sequence of "counting modalities" none of which is expressible in the temporal logic generated by...
