Title:
Homological Methods in Rewriting
Abstract:
It is well-known that some equational theories such as groups or boolean algebras can be defined by fewer equational axioms than the original axioms. However, it is not easy to determine if a given set of axioms is the smallest or not. In this talk, we will see a way to find a lower bound of the number of axioms. The inequality that gives the lower bound is obtained by analyzing the algebraic structure, called the homology group, associated with the given equational theory. I will explain how equational theories and rewriting systems relate to abstract algebra, what homology groups in general settings are like, and what the homology groups of equational theories give us. Also, a connection to E-unification will be given.

16th Logical and Semantic Frameworks with Applications - LSFA 2021
23-24 July 2021
https://mat.unb.br/lsfa2021
Affiliated to FSCD 2021, Buenos Aires, Argentina (Online)
Second Call For Papers
——————————————————//——————————————————
Logical and semantic frameworks are formal languages used to represent
logics, languages and systems. These frameworks provide foundations
for the formal specification of systems and computational languages,
supporting tool development and reasoning. The LSFA series' objective
is to put together theoreticians and practitioners to promote new
techniques and results, from the theoretical side, and feedback on the
implementation and use of such techniques and results, from the
practical side.
See lsfa.cic.unb.br for more information.
LSFA topics of interest include, but are not limited to:
* Automated deduction
* Applications of logical and semantic frameworks
* Computational and logical properties of semantic frameworks
* Formal semantics of languages and systems
* Implementation of logical and semantic frameworks
* Lambda and combinatory calculi
* Logical aspects of computational complexity
* Logical frameworks
* Process calculi
* Proof theory
* Semantic frameworks
* Specification languages and meta-languages
* Type theory
Submissions
Contributions should be written in English and submitted in full paper
(with a maximum of 16 pages) or short papers (with a maximum of 6
pages). They must be unpublished and not submitted simultaneously for
publication elsewhere. The papers should be prepared in LaTeX using
the EPTCS style. The submission should be in the form of a PDF file
uploaded to Easychair:
https://easychair.org/conferences/?conf=lsfa2021
The pre-proceedings, containing the reviewed extended abstracts, will
be handed out at event registration. After the meeting, the authors
will be invited to submit full versions of their works for the
post-proceedings publication. At least one of the authors should
register for the conference. Presentations should be in English.
According to the submissions' quality, the chairs will promote the
further publication of journal revised versions of the
papers. Previous LSFA Special Issues have been published in journals
such as The Logical J. of the IGPL, Theoretical Computer Science and
Mathematical Structures in Computer Sciences (see the LSFA page
http://lsfa.cic.unb.br).
Important dates
* Abstract: Monday 26th April
* Submission: Sunday 2nd May
* Notification: Friday 4th June

CALL FOR PAPERS
WoLLIC 2021
27th Workshop on Logic, Language, Information and Computation
October 5 to 8, 2021
ORGANISATION
Universidade de São Paulo, Brazil
University College London, UK
Centro de Informática, Universidade Federal de Pernambuco, Brazil
CALL FOR PAPERS
WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers. The twenty-seventh WoLLIC will be held online from October 5 to 8, 2021. It is scientifically sponsored by the Association for Symbolic Logic (ASL), the Interest Group in Pure and Applied Logics (IGPL), the The Association for Logic, Language and Information (FoLLI), the European Association for Theoretical Computer Science (EATCS), ACM Special Interest Group on Logic and Computation (ACM-SIGLOG) (TBC), the Sociedade Brasileira de Computação (SBC), and the Sociedade Brasileira de Lógica (SBL).
PAPER SUBMISSION
Contributions are invited on all pertinent subjects, with particular interest in cross-disciplinary topics. Typical but not exclusive areas of interest are: foundations of computing and programming; novel computation models and paradigms; broad notions of proof and belief; proof mining, type theory, effective learnability; formal methods in software and hardware development; logical approach to natural language and reasoning; logics of programs, actions and resources; foundational aspects of information organization, search, flow, sharing, and protection; foundations of mathematics; philosophy of mathematics; philosophical logic; philosophy of language. Proposed contributions should be in English, and consist of a scholarly exposition accessible to the non-specialist, including motivation, background, and comparison with related works. Articles should be written in the LaTeX format of LNCS by Springer (see authors instructions at http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0 <http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0>). They must not exceed 12 pages, with up to 5 additional pages for references and technical appendices. The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings. It is expected that each accepted paper be presented at the meeting by one of its authors. (At least one author is required to pay the registration fee before granting that the paper will be published in the proceedings.) Papers must be submitted electronically at the WoLLIC 2020 EasyChair website (https://easychair.org/conferences/?conf=wollic2021 <https://easychair.org/conferences/?conf=wollic2021>).
PROCEEDINGS
The proceedings of WoLLIC 2021, including both invited and contributed papers, will be published in advance of the meeting as a volume in Springer's LNCS series. In addition, abstracts will be published in the Conference Report section of the Logic Journal of the IGPL, and selected contributions will be published (after a new round of reviewing) as a special post-conference WoLLIC 2021 issue of a scientific journal (to be confirmed).

SPECIAL SESSION: SCREENING OF MOVIES ABOUT MATHEMATICIANS
It is planned to have a special session with the exhibition of a one-hour documentary film about a remarkable mathematician whose contributions were recognized with a Fields Medal just a few years before her untimely death. It is a joint production (still on its course) of The Mathematical Sciences Research Institute (MSRI) and George Csicsery (Zala Films): ‘Secrets of the Surface - The Mathematical Vision of Maryam Mirzakhani’. “The biographical film is about Maryam Mirzakhani, a brilliant woman, and Muslim immigrant to the United States who became a superstar in her field. The story of her life will be complemented with sections about Mirzakhani’s mathematical contributions, as explained by colleagues and illustrated with animated sequences. Throughout, we will look for clues about the sources of Mirzakhani’s insights and creativity." (http://www.zalafilms.com/secrets/ <http://www.zalafilms.com/secrets/>)
