\title{Arrow and Gibbard-Satterthwaite}
\author{Tobias Nipkow}
\maketitle

\begin{abstract}
This article formalizes two proofs of Arrow's impossibility theorem
due to Geanakoplos and derives the Gibbard-Satterthwaite theorem as a
corollary. One formalization is based on utility functions, the other
one on strict partial orders.
\end{abstract}

\noindent
For an article about these proofs see
