Abstract
In this paper we introduce a notion of a regular expression over infinite alphabets and show that a language is definable by an infinite alphabet regular expression if and only if it is acceptable by finite-state unification based automaton – a model of computation that is tightly related to other models of automata over infinite alphabets.
