}The theory of the natural numbers with linear order and monadic predicates underlies propositional linear temporal logic. To study temporal logics that are suitable for reasoning about real-time systems, we combine this classical theory of infinite state sequences with a theory of discrete time, via a monotonic function that maps every state to its time. The resulting theory of timed state sequences is shown to be decidable, albeit nonelementary, and its expressive power is characterized by…

Logics for Real Time: Decidability and Complexity
- Computer ScienceFundam. Informaticae

This work defines a quantitative temporal logic that is based on a simple modality within the framework of monadic predicate Logic that is as expressive as any logic suggested in the literature.
Time-Bounded Verification

It is shown that, over bounded time intervals, MTL satisfiability and model checking are EXPSPACE-Complete, whereas these problems are decidable but non-elementary for the predicate logics.
Comparing Expressive Power of Timed Logics BTP report
- Computer Science
- 2012
This work attacks the open problems of comparing MTL with timed past and untimed past, and establishes a hierarchy for MTL, based on the largest constant that can appear in the interval constraints, using EF games.
A Decidable Timeout based Extension of Propositional Linear Temporal Logic
- Computer ScienceArXiv
- 2010
It is proved that when TLTL is interpreted over discrete time, it can be embedded in the monadic second order logic with time, and whenTL is interpreting over dense time without the condition of non-zenoness, the resulting logic becomes $\Sigma_1^1$-complete.

This paper analyzes real-time and probabilistic temporal logics which have been widely used in this field and extrapolate the notions of decidability, axiomatizability, expressiveness, model checking, etc. for each logic analysed.
A Logical Characterization of Timed (non-)Regular Languages
- Computer Science, MathematicsMFCS
- 2014
A monadic theory of orders, extending the one introduced by Kamp, is defined, which is expressively equivalent to CLTLoc, and a decidable extension with an arithmetical next operator, which allows the expression of timed non-ω-regular languages.

A unifying framework for the study of real-time logics is developed, and the underlying classical theory of timed state sequences is identified, it is shown to be nonelementarily decidable, and its complexity and expressiveness are used as a point of reference.

This work proposes a system of temporal logic, RTCTL (Real-Time Computation Tree Logic), that allows the melding of qualitative temporal assertions together with real-time constraints to permit specification and reasoning at the twin levels of abstraction: qualitative and quantitative.

This paper presents abbreviations which allow the expression of the most important real-time properties and some other important requirements of PTL and shows that they are easy to use and that the induced complexity cost is the same as the complexity of the other real- time logics.
