Call for Papers, PxTP 2021
The Seventh International Workshop on
Proof eXchange for Theorem Proving (PxTP)
https://pxtp.gitlab.io/2021
21 July 2021, online
associated with the CADE-28 conference
## Background
The PxTP workshop brings together researchers working on various
aspects of communication, integration, and cooperation between
reasoning systems and formalisms.
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
Topics of interest for this workshop include all aspects of
cooperation between reasoning tools, whether automatic or interactive.
More specifically, some suggested topics are:
* applications that integrate reasoning tools (ideally with
certification of the result);
* interoperability of reasoning systems;
* translations between logics, proof systems, models;
* distribution of proof obligations among heterogeneous reasoning
tools;
* algorithms and tools for checking and importing (replaying,
reconstructing) proofs;
* proposed formats for expressing problems and solutions for different
classes of logic solvers (SAT, SMT, QBF, first-order logic,
higher-order logic, typed logic, rewriting, etc.);
* meta-languages, logical frameworks, communication methods,
standards, protocols, and APIs related to problems, proofs, and
models;
* comparison, refactoring, transformation, migration, compression and
optimization of proofs;
* data structures and algorithms for improved proof production in
solvers (e.g., efficient proof representations);
* (universal) libraries, corpora and benchmarks of proofs and
theories;
* alignment of diverse logics, concepts and theories across systems
and libraries;
* engineering aspects of proofs (e.g., granularity, flexiformality,
persistence over time);
* proof certificates;
* proof checking;
* mining of (mathematical) information from proofs (e.g., quantifier
instantiations, unsat cores, interpolants, ...);
* reverse engineering and understanding of formal proofs;
* universality of proofs (i.e. interoperability of proofs between
different proof calculi);
* origins and kinds of proofs (e.g., (in)formal, automatically
generated, interactive, ...)
* Hilbert's 24th Problem (i.e. what makes a proof better than
another?);
* social aspects (e.g., community-wide initiatives related to proofs,
cooperation between communities, the future of (formal) proofs);
* applications relying on importing proofs from automatic theorem
provers, such as certified static analysis, proof-carrying code, or
certified compilation;
* application-oriented proof theory;
* practical experiences, case studies, feasibility studies.
## Submissions
Researchers interested in participating are invited to submit either an
extended abstract (up to 8 pages) or a regular paper (up to 15 pages).
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.
Submitted papers should describe previously unpublished work, and must
be prepared using the LaTeX EPTCS class (http://style.eptcs.org).
Papers will be submitted via EasyChair, at the PxTP'2021 workshop page
(https://easychair.org/conferences/?conf=pxtp-7).
Accepted regular papers will appear in an EPTCS volume.
