Title
Equations between regular terms and an application to process logic
Abstract
Regular terms with the Kleene operations &ugr;,;, and * can be thought of as operators on languages, generating other languages. An equation r1 &equil; r2 between two such terms is said to be satisfiable just in case languages exist which make this equation true. We show that the satisfiability problem even for *-free regular terms is undecidable. Similar techniques are used to show that a very natural extension of the Process Logic of Harel, Kozen and Parikh is undecidable.
