RWTH Aachen University, in German Rheinisch-Westfälische Technische Hochschule Aachen, is a German public research university located in Aachen, North Rhine-Westphalia, Germany. With more than 47,000 students enrolled in 144 study programs, it is the largest technical university in Germany.
In logic, linear temporal logic or linear-time temporal logic (LTL) is a modal temporal logic with modalities referring to time. In LTL, one can encode formulae about the future of paths, e.g., a condition will eventually be true, a condition will be true until another fact becomes true, etc. It is a fragment of the more complex CTL*, which additionally allows branching time and quantifiers. LTL is sometimes called propositional temporal logic, abbreviated PTL. In terms of expressive power, linear temporal logic (LTL) is a fragment of first-order logic.
A Kripke structure is a variation of the transition system, originally proposed by Saul Kripke, used in model checking to represent the behavior of a system. It consists of a graph whose nodes represent the reachable states of the system and whose edges represent state transitions, together with a labelling function which maps each node to a set of properties that hold in the corresponding state. Temporal logics are traditionally interpreted in terms of Kripke structures.
In theoretical computer science, a stutter bisimulation is a relationship between two transition systems, abstract machines that model computation. It is defined coinductively and generalizes the idea of bisimulations. A bisimulation matches up the states of a machine such that transitions correspond; a stutter bisimulation allows transitions to be matched to finite path fragments.

The International Conference on Concurrency Theory (CONCUR) is an academic conference in the field of computer science, with focus on the theory of concurrency and its applications. It is the flagship conference for concurrency theory according to the International Federation for Information Processing Working Group on Concurrency Theory. The conference is organised annually since 1988. Since 2015, papers presented at CONCUR are published in the LIPIcs–Leibniz International Proceedings in Informatics, a "series of high-quality conference proceedings across all fields in informatics established in cooperation with Schloss Dagstuhl –Leibniz Center for Informatics". Before, CONCUR papers were published in the series Lecture Notes in Computer Science.
Ralf Steinmetz is a German computer scientist and electrical engineer. He is professor of multimedia communication at the Technische Universität Darmstadt.
In model checking, a branch of computer science, linear time properties are used to describe requirements of a model of a computer system. Example properties include "the vending machine does not dispense a drink until money has been entered" or "the computer program eventually terminates". Fairness properties can be used to rule out unrealistic paths of a model. For instance, in a model of two traffic lights, the liveness property "both traffic lights are green infinitely often" may only be true under the unconditional fairness constraint "each traffic light changes colour infinitely often".
Christel Baier is a German theoretical computer scientist known for her work in model checking, temporal logic, and automata theory.
