....exists many proposals for logics that extend LTL (sometimes greatly) without being essentially more di cult for model checking. Four well known examples are CTL # (seen in Section 3.1. 3) LTL extended with (essentially) Bchi automata [Wol83] LTL with existential quanti cation over propositions [SVW87] and LTL Past that we consider in Section 5 below. # 4.1 Fragments of LTL 4.1.1 Restricted set of modalities Some fragments of LTL are obtained by restricting the allowed modalities. e.g. L(U) is LTL where U is the only allowed modality (X is not allowed but F is since it can be expressed ....

....is trust monotony: the better the experiences with something or someone, the higher the trust . This type of relative property can be expressed in our language, whereas in standard forms of temporal logic different alternative histories cannot be compared; for example, in LTL or Quantified LTL [19] no quantification over traces is possible. For the temporal trace language TTL a software environment has been developed including an editor to specify dynamic properties and a (model) checker to check given traces against dynamic properties specified in TTL. As the current paper focuses on ....

.... for LTL Past and mu calculus Past in [17, 24, 12, 13] these logics have PSPACE complete verification problems) N can be encoded in richer formalisms, e.g. QPLTL (PLTL with arbitrary quantification over propositional variables) but QPLTL and QLTL have non elementary verification problems [22]. Chop is another modality where part of the computation can be forgotten: here too verification becomes non elementary [10, 20] Plan of the paper. We provide the necessary definitions in 2, study succinctness issues in 3, and provide automata theoretic decision procedures for NLTL in 4. Model ....
