This paper compares the descriptive power of three programming logics by examining the elementary equivalence relations induced on nondeterministic state transition systems by these logics. These three comprise propositional dynamic logic introduced by Fischer and Ladner, Hennessy-Milner logic and a new logic called regular trace logic intended for study on behavioural specifications for concurrent programs. The authors consider, besides the elementary equivalence relations mentioned above, the notions of bisimilarity of Park and Ogden, Milnor’s observation equivalence, failure equivalence and trace equivalence.
