Isar is an extension of Isabelle with structured proofs in a
|
|
|
21 |
stylized language of mathematics. These proofs are readable for both a human
|
|
|
22 |
and a machine.

This document is a very compact introduction to structured proofs in
|
|
13330
|
25 |
Isar/HOL, an extension of Isabelle/HOL~\cite{LNCS2283}. A detailed
|
|
13294
|
26 |
exposition of this material can be found in Markus Wenzel's PhD
|
|
13307
|
27 |
thesis~\cite{Wenzel-PhD} and the Isar reference manual~\cite{Isar-Ref-Man}.
