-\begin{abstract} 
-There are numerous textbooks on regular languages. Nearly all of them
-introduce the subject by describing finite automata and only mentioning on the
-side a connection with regular expressions. Unfortunately, automata are difficult
-to formalise in HOL-based theorem provers. The reason is that
-they need to be represented as graphs, matrices or functions, none of which
-are inductive datatypes. Also convenient operations for disjoint unions of
-graphs and functions are not easily formalisiable in HOL. In contrast, regular
-expressions can be defined conveniently as a datatype and a corresponding
-reasoning infrastructure comes for free. We show in this paper that a central
-result from formal language theory---the Myhill-Nerode theorem---can be
-recreated using only regular expressions.
