LTL with the freeze quantifier and register automata

S Demri, R Lazić - ACM Transactions on Computational Logic (TOCL), 2009 - dl.acm.org
A data word is a sequence of pairs of a letter from a finite alphabet and an element from an
infinite set, where the latter can only be compared for equality. To reason about data words …

Model checking real-time systems

P Bouyer, U Fahrenberg, KG Larsen, N Markey… - Handbook of model …, 2018 - Springer
This chapter surveys timed automata as a formalism for model checking real-time systems.
We begin with introducing the model, as an extension of finite-state automata with real …

Complexity hierarchies beyond elementary

S Schmitz - ACM Transactions on Computation Theory (TOCT), 2016 - dl.acm.org
We introduce a hierarchy of fast-growing complexity classes and show its suitability for
completeness statements of many nonelementary problems. This hierarchy allows the …

Some recent results in metric temporal logic

J Ouaknine, J Worrell - International Conference on Formal Modeling and …, 2008 - Springer
Abstract Metric Temporal Logic (MTL) is a widely-studied real-time extension of Linear
Temporal Logic. In this paper we survey results about the complexity of the satisfiability and …

On the decidability and complexity of metric temporal logic over finite words

J Ouaknine, J Worrell - Logical Methods in Computer Science, 2007 - lmcs.episciences.org
Metric Temporal Logic (MTL) is a prominent specification formalism for real-time systems. In
this paper, we show that the satisfiability problem for MTL over finite timed words is …

Timed temporal logics

P Bouyer, F Laroussinie, N Markey, J Ouaknine… - … , Algorithms, Logics and …, 2017 - Springer
Since the early 1990's, classical temporal logics have been extended with timing constraints.
While temporal logics only express contraints on the order of events, their timed extensions …

Safety metric temporal logic is fully decidable

J Ouaknine, J Worrell - International conference on tools and algorithms for …, 2006 - Springer
Abstract Metric Temporal Logic (MTL) is a widely-studied real-time extension of Linear
Temporal Logic. In this paper we consider a fragment of MTL, called Safety MTL, capable of …

Alternation-free modal mu-calculus for data trees

M Jurdzinski, R Lazic - 22nd Annual IEEE Symposium on Logic …, 2007 - ieeexplore.ieee.org
An alternation-free modal ì-calculus over data trees is introduced and studied. A data tree is
an unranked ordered tree whose every node is labelled by a letter from a finite alphabet and …

Runtime verification of temporal properties over out-of-order data streams

D Basin, F Klaedtke, E Zălinescu - … 2017, Heidelberg, Germany, July 24-28 …, 2017 - Springer
We present a monitoring approach for verifying systems at runtime. Our approach targets
systems whose components communicate with the monitors over unreliable channels …
