A production on T* is a rewriting rule sa?s' for all a? T*, where s, s' are strings in T* with a' lexicographically earlier than s. Any finite collection of productions is called a system. This note shows that any system that is consistent, complete, and has the nonprefix property uniquely represents an automaton. This formulation characterizes automata as recognition devices in terms of a set of rewriting rules, similar to the characterizatibn of automata as generating devices by grammars.
Complete system, consistent system, nonprefix property, reduced string, reduced system.
