Real-time and Probabilistic Temporal Logics: An Overview [article]

Savas Konur
2011 arXiv   pre-print
Although numerous logics have been introduced for the formal specification of real-time and complex systems, an up to date comprehensive analysis of these logics does not exist in the literature.  ...  We extrapolate the notions of decidability, axiomatizability, expressiveness, model checking, etc. for each logic analysed. We also provide a comparison of features of the temporal logics discussed.  ...  In particular, Duration Calculus [16] is an extension of interval temporal logic with "a calculus to specify and reason about properties of state durations".  ...

Causality–Complexity–Consistency: Can Space-Time Be Based on Logic and Computation? [chapter]

Ämin Baumeler, Stefan Wolf
2017 Time in Physics  
In the same context-free spirit, we connect the logical reversibility of an evolution to the second law of thermodynamics and the arrow of time.  ...  Refraining from assuming space-time as given a priori has a number of consequences. First, the usual definitions of randomness depend on a causal structure and turn meaningless.  ...  ACKNOWLEDGMENTS The present work was supported by the Swiss National Science Foundation (SNF), the National Centre of Competence in Research "Quantum Science and Technology" (QSIT), the COST action on  ...

Interval logics and their decision procedures Part II: A real-time interval logic

Y Ramakrishna
1996 Theoretical Computer Science  
In a companion paper, we presented an interval logic, and showed that it is elementarily decidable.  ...  The latter problem was shown decidable by Alur and Dill in a landmark paper, in which this real-time extension of w-automata was introduced.  ...  Acknowledgements We thank Rajeev Alur for his comments on the conference version of this paper.  ...

Cryptographic protocol logic: Satisfaction for (timed) Dolev–Yao cryptography

Simon Kramer
2008 The Journal of Logic and Algebraic Programming  
This article is about a breadth-first exploration of logical concepts in cryptography and their linguistic abstraction and model-theoretic combination in a comprehensive logical system, called CPL (for  ...  The distinguishing feature of CPL is that it unifies and refines a variety of existing approaches.  ...  Acknowledgements I would like to thank Sergei Artëmov, Mika Cohen, Ralf Küsters, and Lawrence Moss for their valuable criticism.  ...

A real-time interval logic and its decision procedure [chapter]

Y. S. Ramakrishna, L. K. Dillon, L. E. Moser, P. M. Melliar-Smith, G Kutty
1993 Lecture Notes in Computer Science  
Real-Time Future Interval Logic is a visual logic in which formul have a natural graphical representation, resembling timing diagrams.  ...  The decision procedure forms the core of a proof checker for the logic that we have recently implemented. The logic does not admit instantaneous states, and is invariant under realtime stuttering.  ...  We thank Rajeev Alur for useful discussions, and for helpful comments on an earlier draft of the paper.  ...

Modal and temporal logics for abstract space–time structures

Sara L. Uckelman, Joel Uckelman
2007 Studies in history and philosophy of modern physics  
This definition of necessity can be formalized and treated within a logical framework.  ...  We give a survey of the several known modal and temporal logics of abstract space-time structures based on the real numbers and the integers, considering three different accessibility relations between  ...  A Kripke model M is a tuple W, R, V , where W is a set of points (which can be thought of as 'worlds' or 'times'), R is a binary relation on W , and V is a function from propositional variables to ℘(W  ...

Dynamic epistemic logic in update logic

Guillaume Aucher
2016 Journal of Logic and Computation  
Finally, we show that DEL with a finite number of atomic events is as expressive as epistemic logic.  ...  We show that Dynamic Epistemic Logic (DEL) is a substructural logic and that it is an extension of the update logic introduced in the companion article [12] .  ...  Acknowledgements I thank Olivier Roy and Ole Hjortland for inviting me to the Munich Meeting on Sub-structural Epistemic Logic (January 2013), which was very inspiring.  ...

In this paper, we propose default logic for diagnostic of Discrete Time System (DTS) by focusing on automatic synthesis of the signaling pathways from factors within the cell.  ...  By choosing an adequate representation of biological knowledge, the "reasoning" is able to assign in acquisition of the facts and extract interactions necessary for the synthesis of the signaling pathways  ...  Jean-Charles Faye and C.R.

"Logic Wins!" [chapter]

Jean Goubault-Larrecq
2009 Lecture Notes in Computer Science  
Clever algorithm design is sometimes superseded by simple encodings into logic. We apply this motto to a few case studies in the formal verification of security properties.  ...  Approximating a Hoare logic such as [7] through Horn clauses is probably a good starting point for this.  ...  Finally, when one comes to hardware circuits, one is led to evaluate the impact of timing attacks (which we cannot yet, since time was left implicit in our model-only simulation cycles, not time, were  ...

Models and temporal logical specifications for timed component connectors

Farhad Arbab, Christel Baier, Frank de Boer, Jan Rutten
2006 Journal of Software and Systems Modeling  
In this paper, we present an operational semantics for the channel-based component connectors of Reo in terms of Timed Constraint Automata and introduce a temporal-logic for specification and verification  ...  Effective, flexible component composition by itself still poses a challenge today and yet the special nature of real-time constraints makes component-based construction of real-time systems even more demanding  ...  To specify a desired coordination mechanism, we use a variant of linear temporal logic (LTL) [22, 27] with real-time constraints, which we call timed scheduleddata-stream logic (TSDSL) and has a semantics  ...
