ProofCheck: Checking Proofs Written in TeX
Welcome to the web site that helps you to use TeX
to write complete mathematical proofs that you can check with a
The basic structure of the checking program is very simple: each step of
a proof to be checked is
one rule after another from a long list rules of inference,
in search of a match. The step is checked if
a match is found. A proof is checked if all its steps check.
ProofCheck is based on syntactical ideas of
A. P. Morse.
Its guiding philosophy is that complete formality is to be achieved
using as little formalism and deviation from accepted mathematical notation
ProofCheck is described in a paper in
The PracTeX Journal,
and in a poster presentation at
a Python conference, PyCon2012.
