\title{Abstract Soundness}
\author{Jasmin Christian Blanchette, Andrei Popescu, and Dmitriy Traytel}

\maketitle

\begin{abstract}
This is a formalized coinductive account of the abstract development of
Brotherston et al.\ \cite{brotherston-et-al-2012}, in a slightly more general
form since we work with arbitrary infinite proofs, which may be acyclic. This
work is described in detail in an article by the authors
\cite{blanchette-et-al-2017-co-methods}. The abstract proof can be
instantiated for various formalisms, including first-order logic with
inductive predicates.
