21 July 2021, The Seventh International Workshop on Proof eXchange for Theorem Proving (PxTP 2021), Virtual

Date: Wednesday 21 July 2021
Location: Virtual
Deadline: Wednesday 21 April 2021

The progress in computer-aided reasoning, both automatic and interactive, during the past decades, has made it possible to build deduction tools that are increasingly more applicable to a wider range of problems and are able to tackle larger problems progressively faster. In recent years, cooperation of such tools in larger verification environments has demonstrated the potential to reduce the amount of manual intervention. Examples include the Sledgehammer tool providing an interface between Isabelle and (untrusted) automated provers, and collaboration of the HOL Light and Isabelle systems in the formal proof of the Kepler conjecture.

Cooperation between reasoning systems relies on availability of theoretical formalisms and practical tools for exchanging problems, proofs, and models. The PxTP workshop strives to encourage such cooperation by inviting contributions on suitable integration, translation, and communication methods, standards, protocols, and programming interfaces. The workshop welcomes developers of automated and interactive theorem proving tools, developers of combined systems, developers and users of translation tools and interfaces, and producers of standards and protocols. We are interested both in success stories and descriptions of current bottlenecks and proposals for improvement.

Topics of interest for this workshop include all aspects of cooperation between reasoning tools, whether automatic or interactive. Researchers interested in participating are invited to submit either an extended abstract (up to 8 pages) or a regular paper (up to 15 pages). Submitted papers should describe previously unpublished work, and must be prepared using the LaTeX EPTCS class. Submissions will be refereed by the program committee, which will select a balanced program of high-quality contributions. Short submissions that could stimulate fruitful discussion at the workshop are particularly welcome. We expect that one author of every accepted paper will present their work at the workshop.
