Proof Technologies specialise in cutting-edge mathematical proof software for use in mathematics and the formal verification of computer hardware/software. We also provide consultancy in safety-critical software development and functional programming.
We produce the open source HOL Zero theorem prover. This has a $100 bounty reward for soundness flaws!
We produce the open source Tactician, a utility for refactoring HOL Light tactic proof scripts.
We have written an extensive glossary of HOL-related terminology. This covers the basic concepts required to understand the HOL logic and its implementation in theorem provers.
