Revised: 26 April 1999
An illustration of coinduction in terms of a notion of weak bisimilarity is presented. First, an operational semantics for while programs is defined in terms of a final automaton. It identifies any two programs that are weakly bisimilar, and induces in a canonical manner a compositional model . Next is proved by coinduction.
Mathematics Subject Classification: 68Q10 / 68Q55
