Approximating a Behavioural Pseudometric without Discount for Probabilistic Systems

Franck van Breugel ; Babita Sharma ; James Worrell.

Desharnais, Gupta, Jagadeesan and Panangaden introduced a family of behavioural pseudometrics for probabilistic transition systems. These pseudometrics are a quantitative analogue of probabilistic bisimilarity. Distance zero captures probabilistic bisimilarity. Each pseudometric has a discount&nbsp;[&hellip;]

On the Expressiveness and Monitoring of Metric Temporal Logic

Hsi-Ming Ho ; Joël Ouaknine ; James Worrell.

It is known that Metric Temporal Logic (MTL) is strictly less expressive than the Monadic First-Order Logic of Order and Metric (FO[<, +1]) when interpreted over timed words; this remains true even when the time domain is bounded a priori. In this work, we present an extension of MTL with the same&nbsp;[&hellip;]
