# The meta theory of the Incredible Proof Machine

 Title: The meta theory of the Incredible Proof Machine Authors: Joachim Breitner (joachim /at/ cis /dot/ upenn /dot/ edu) and Denis Lohner Submission date: 2016-05-20 Abstract: The Incredible Proof Machine is an interactive visual theorem prover which represents proofs as port graphs. We model this proof representation in Isabelle, and prove that it is just as powerful as natural deduction.
