A temporal logic of causality (TLC) was introduced by Alur, Penczekand Peled in [1]. It is basically a linear time temporal logic
interpreted over Mazurkiewicz traces which allows quantification over
causal chains. Through this device one can directly formulate causality
properties of distributed systems. In this paper we consider an
extension of TLC by strengthening the chain quantification operators.
We show that our logic TLC adds to the expressive power of TLC.
We do so by defining an Ehrenfeucht-Fraissé game to capture the expressive
power of TLC. We then exhibit a property and by means of
this game prove that the chosen property is not definable in TLC. We
then show that the same property is definable in TLC. We prove in
fact the stronger result that TLC is expressively stronger than TLC
exactly when the dependence relation associated with the underlying
trace alphabet is not transitive.
