Abstract

We compare the expressiveness of variants of Metric Temporal Logic (MTL) obtained by adding the past operators ‘S’ and $‘S_I ’$. We consider these variants under the “pointwise" and “continuous" interpretations over both finite and infinite models. Among other results, we show that for each of these variants the continuous version is strictly more expressive than the pointwise version. We also prove a counterfreeness result for MTL which helps to carry over some results from [3] for the case of infinite models to the case of finite models.
