MFCS 2026 - First Call for Papers
========================================================
The 51th conference on Mathematical Foundations of Computer Science (MFCS) will take place in:
Paris, France August 24th-28th, 2026
MFCS is among the conferences with the longest history in the field — the first conference in the series was held already in 1972. Traditionally, the conference moved between the Czech Republic, Poland, and Slovakia; since 2013, the conference has traveled around Europe.
The conference will be preceded, on August 23, by the Young Research Forum Workshop intended for students and postdocs.
NEW: Up to 10 papers will be accepted by the program committee, for which no presence onsite is required.
========================================================
Important dates and information
========================================================
Submissions: April 24th, 2026
Author notification: June 19th, 2026
Camera-ready version: June 26th, 2026
Conference: August 24th-28th, 2026 (YRF Workshop on August 23rd, afternoon)
Deadlines are firm; late submissions will not be considered. All dates are AoE.
Conference website: https://mfcs2026.irif.fr/
========================================================
Submission guidelines
========================================================
1) Papers must present original research on the theory of computer science. No prior publication and no simultaneous submission to other publication outlets (either a conference or a journal) is allowed. Authors are encouraged to also make full versions of their submissions freely accessible in an on-line repository such as arXiv.
2) Submissions take the form of an extended abstract of up-to 12 pages (LIPIcs document class), excluding title page, references and a clearly labelled appendix. The appendix may consist either of omitted proofs or of a full version of the submission, and it will be read at the discretion of program committee members. The extended abstract has to present the merits of the paper and its main contributions clearly, and describe the key concepts and technical ideas used to obtain the results. Submissions must provide the proofs which can enable the main mathematical claims of the paper to be verified.
3) Submissions authored or co-authored by members of the program committee are allowed.
4) At the time of submission, authors may declare that they are unable to attend the conference in Paris and therefore cannot give an in-person presentation. This choice will not influence the evaluation of submissions by the Program Committee. The Program Committee will rank all papers irrespective of their presentation status. Approximately 80 papers will be selected for in-person presentation, and up to 10 papers will be accepted without presentation. All accepted papers will be published in the same proceedings. This option is intended for authors who wish to publish their results at the conference but, for various reasons (e.g., family or financial constraints), are unable to attend the conference in person.
5) At least one author of each accepted paper with presentation is expected to register for the conference, and give the talk in-person. At least one author of each accepted paper without in-person presentation is expected to register for the conference for a reduced fee, and for each such paper the authors are expected to provide a pre-recorded video of the paper presentation that will be made available on-line during the conference. (Pre-recorded videos of the other papers are optional.)
6) Papers authored only by students should be marked as such at the time of submission in order to be eligible for the best student paper award.
7) MFCS proceedings are published in the Leibniz International Proceedings in Informatics (LIPIcs) series. The camera-ready version of accepted papers will need to comply with the LIPIcs style.

[Caml-list] Call For Papers: 6th Workshop on Program Equivalence and Relational Reasoning (PERR2026 @ CAV/FLOC)
[with apologies for cross-postings]
======================================================================
6th Workshop on Program Equivalence and Relational Reasoning
24 July 2026 at ISCTE campus, Lisbon, Portugal
associated with CAV 2026 at FLOC 2026
======================================================================
Submission Deadline: Friday, 24 April, 2026 (AoE)
Submit at: https://submissions.floc26.org/perr
CALL FOR PAPERS/PRESENTATIONS
PERR is an annual international workshop dedicated to the formal verification of program equivalence and related relational problems. It is the 6th in a series of meetings that bring together researchers from different areas interested in equivalence and related questions. PERR 2026 will be a workshop at FLOC 2026, and a satellite event to CAV 2026.
Program equivalence is arguably one of the most interesting and at the same time important problems in formal verification. It is a cross-cutting topic that has attracted the interest of several research communities: the field of denotational (game) semantics, deductive software verification, bounded model checking, specification inference, software evolution and regression testing, etc.
The goal of the workshop is to bring researchers of the different fields in touch and to stimulate an exchange of ideas leading to forging a community working on PERR. It welcomes contributions from the topics mentioned above but is also open to new questions regarding program equivalence. This includes related research areas of relational reasoning like program refinement or the verification of hyperproperties, in particular of secure information flow.
- regression verification
- program equivalence
- equivalence of higher order programs
- product programs, relational calculi
- verification of hyperproperties
- program refinement, refinement calculus
- specification of differences between programs
- inferring semantic differences between programs
- transformation validation
- correct compiler transformations
- automata bisimulation
- AI-supported equivalence checking
- relational properties of AI-based systems
- code equivalence checking in teaching and marking
This is an informal workshop that welcomes work in progress, overviews of more extensive work, programmatic or position papers and tool presentations.
SUBMISSION GUIDELINES
We invite two types of submissions:
- Regular papers. Regular papers should be at most 15 pages (excluding references). They should present original research results, tools, or case studies.
- Extended Abstracts. Extended abstracts should be at most 3 pages (excluding references). They should introduce work that has recently been published or is under review, or work in progress.
Submissions should be made using the PERR 2026 submission site:
Submissions must be a single PDF file, in LNCS format.
The workshop will have informal proceedings, posted on the webpage, and speakers will be asked to consider submitting papers towards a post-proceedings volume.
IMPORTANT DATES
Submission Deadline: Friday, 24 April, 2026 (AoE)

and not submitted elsewhere. System descriptions are limited to 15
pages, excluding references. Shorter papers are welcome and will be
given equal consideration. A system description must present new
software tools, or significantly new versions of such tools, in which
FSCD topics play an important role. An archive of the code with
instructions on how to install and run the tool must be submitted. In
addition, a webpage where the system can be experimented with should be
provided.
One author of each accepted paper is expected to register and present
the work in person at the conference. In case that this is not possible,
online presentation will be arranged, but in person registration will
still be required.
BEST PAPER AWARD BY JUNIOR RESEARCHERS
--------------------------------------
The programme committee will select a paper in which at least one author
is a junior researcher, i.e., either a student or someone whose PhD
award date is less than three years from the first day of the meeting.
