\title{Concrete Semantics}
\author{Tobias Nipkow \& Gerwin Klein}
\maketitle

\begin{abstract}
This document presents formalizations of the semantics of a simple imperative programming language together with a number of applications: a compiler, type systems, various program analyses and abstract interpreters. These theories form the basis of the book \emph{Concrete Semantics with Isabelle/HOL} by Nipkow and Klein \cite{NipkowK2014}.
