2017 arXiv   pre-print
We propose a method for the decomposition of modal formulae on processes with nondeterminism and probability with respect to Structural Operational Semantics.  ...  To deal with the probabilistic behavior of processes, and thus with the decomposition of formulae characterizing it, we introduce a SOS-like machinery allowing for the specification of the behavior of  ...  Conclusions We developed a modal decomposition of formulae in L and its subclasses L r , L + , on nondeterministic probabilistic processes.  ...

Logical Characterization of Bisimulation Metrics

Valentina Castiglioni, Daniel Gebler, Simone Tini
2016 Electronic Proceedings in Theoretical Computer Science  
Bisimulation metrics provide a robust and accurate approach to study the behavior of nondeterministic probabilistic processes.  ...  In this paper, we propose a logical characterization of bisimulation metrics based on a simple probabilistic variant of the Hennessy-Milner logic.  ...  The modal logic L We introduce the modal logic L of [19] , which extends HML [41] with a probabilistic choice modality that allows us to express the behavior of probabilistic distributions over processes  ...

Book Introduction by the Author: Semantics of Probabilistic Processes An Operational Approach

Yuxin Deng
2015 Bulletin of the European Association for Theoretical Computer Science  
In "Semantics of Probabilistic Processes" [4] we adopt an operational approach to describing the behaviour of nondeterministic and probabilistic processes.  ...  The second part sets up a general testing framework and specialises it to probabilistic processes with nondeterministic behaviour. The resulting testing semantics is treated in depth.  ...  My research on probabilistic concurrency theory has been sponsored by the National Natural Science Foundation of China under grants 61173033 and 61261130589.  ...

Characterising Probabilistic Processes Logically [chapter]

Yuxin Deng, Rob van Glabbeek
2010 Lecture Notes in Computer Science  
In this paper we work on (bi)simulation semantics of processes that exhibit both nondeterministic and probabilistic behaviour.  ...  We propose a probabilistic extension of the modal mu-calculus and show how to derive characteristic formulae for various simulation-like preorders over finite-state processes without divergence.  ...  The first papers on probabilistic concurrency theory [11, 2, 19] proceed by replacing nondeterministic with probabilistic constructs.  ...

We illustrate the methods with an analysis of performance of the probabilistic dining philosophers [10] .  ...  quantitative program logic [14] provides a formal framework in which to promote standard techniques of program analysis to a context where probability and nondeterminism interact, a situation common to probabilistic  ...  Deciding how to choose an appropriate decomposition often depends on the probabilistic invariant properties, and we discuss them next.  ...

Modal Logics are Coalgebraic

C. Cirstea, A. Kurz, D. Pattinson, L. Schroder, Y. Venema
2009 Computer journal  
This paper substantiates the authors' firm belief that the systematic exploitation of this coalgebraic nature will not only have impact on the field of modal logic itself but also lead to significant progress  ...  Coalgebraic semantics, on the other hand, provides a uniform and encompassing view on the large variety of specific logics used in particular domains.  ...  for Segala systems advocated in [24] that distinguishes probabilistic and nondeterministic formulas.  ...

Logical, Metric, and Algorithmic Characterisations of Probabilistic Bisimulation [article]

Yuxin Deng, Wenjie Du
2011 arXiv   pre-print
Many behavioural equivalences or preorders for probabilistic processes involve a lifting operation that turns a relation on states into a relation on distributions of states.  ...  Specifically, we extend the Hennessy-Milner logic and the modal mu-calculus with a new modality, resulting in an adequate and an expressive logic for probabilistic bisimilarity, respectively.  ...  In the belief that a good scientific concept is often elegant, even seen from different perspectives, we consider the lifting operation and probabilistic bisimulation as two concepts in probabilistic concurrency  ...

Furthermore, inspired by the work of Hermanns et al. on probabilistic systems, we provide a sound and complete modal characterisation of fuzzy bisimilarity.  ...  generalises a result on finite-state processes originally established by Baier; (2) the modal characterisation of bisimilarity by Desharnais et al. admits a much simpler completeness proof.  ...  Acknowledgement We thank the anonymous referees for their helpful comments on a preliminary version of the paper.  ...
