\title{\LARGE\bf General Binding Structures in Nominal Isabelle,\\ or How to
  Formalise Core-Haskell}
\maketitle

\maketitle
\begin{abstract} 
Nominal Isabelle is a definitional extension of the Isabelle/HOL theorem
prover. It provides a proving infrastructure for convenient reasoning about
programming language calculi involving bound variables that have names (as
opposed to de-Bruijn indices). In this paper we present an extension of
Nominal Isabelle in order to deal with general binding structures. Such
binding structures are ubiquitous in programming language research and only
very poorly supported with single binders, as for example found in the
lambda-calculus. For our extension we introduce novel definitions of
alpha-equivalence and establish automatically the reasoning infrastructure for
alpha-equated terms. This includes strong induction principles that have the
variable convention already built in.
