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 …

An automata-theoretic approach to constraint LTL

S Demri, D d'Souza - Information and Computation, 2007 - Elsevier
We consider an extension of linear-time temporal logic (LTL) with constraints interpreted
over a concrete domain. We use a new automata-theoretic technique to show PSPACE …

[PDF][PDF] Temporal stream logic modulo theories

B Finkbeiner, P Heim, N Passing - International Conference on …, 2022 - library.oapen.org
Temporal stream logic (TSL) extends LTL with updates and predicates over arbitrary
function terms. This allows for specifying dataintensive systems for which LTL is not …

On the freeze quantifier in constraint LTL: decidability and complexity

S Demri, R Lazić, D Nowak - Information and Computation, 2007 - Elsevier
Constraint LTL, a generalisation of LTL over Presburger constraints, is often used as a
formal language to specify the behavior of operational models with constraints. The freeze …

Linear-time temporal logics with Presburger constraints: an overview★

S Demri - Journal of Applied Non-Classical Logics, 2006 - Taylor & Francis
We present an overview of linear-time temporal logics with Presburger constraints whose
models are sequences of tuples of integers. Such formal specification languages are well …

[PDF][PDF] Algorithmic Properties of First-Order Modal Logics of the Natural Number Line in Restricted Languages.

MN Rybakov, D Shkatov, N Olivetti, R Verbrugge… - AiML, 2020 - philarchive.org
We study algorithmic properties of first-order predicate monomodal logics of the frames (N,<)
and (N,≤) in languages with restrictions on the number of individual variables as well as the …

Concrete domains in logics: a survey

S Demri, K Quaas - ACM SIGLOG News, 2021 - dl.acm.org
In this short survey, we present logical formalisms in which reasoning about concrete
domains is embedded in formulae at the atomic level. These include temporal logics with …

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 …

[PDF][PDF] Reasoning about data repetitions with counter systems

S Demri, D Figueira, M Praveen - Logical Methods in …, 2016 - lmcs.episciences.org
We study linear-time temporal logics interpreted over data words with multiple attributes. We
restrict the atomic formulas to equalities of attribute values in successive positions and to …

Future-looking logics on data words and trees

D Figueira, L Segoufin - International Symposium on Mathematical …, 2009 - Springer
In a data word or a data tree each position carries a label from a finite alphabet and a data
value from an infinite domain. Over data words we consider the logic \sfLTL^↓_1(\rmF), that …
