Instructions for authors

This page outlines the process followed by the journal of Groups, Complexity, Cryptology, from the submission to the publication of a paper. In submitting their work, authors agree to follow these rules.

Submission process

Before submitting a paper to the journal of Groups, Complexity, Cryptology, authors must first post their paper on an open repository, arXiv or HALincluding TeX source files. If asked by arXiv or HAL to select a license, they should select the simple non-exclusive license to distribute, see the note in

Disclaimer This policy is intended to favor both the authors and the journal. For the authors, because availability of their results is not delayed by the review process; for the journal, as the requirement of making preprints available online may lead to higher quality submissions.

After publication of their preprint by arXiv or HAL, papers can be formally submitted to the journal using this link, which requires logging in. If the submitting author already has an account with episciences or with HAL, they can use this account to log in; if they don't have such an account, they will have to create one. Once logged in, the submission process includes the choice of a handling editor from the Editorial Board displayed on the website. Authors should choose exactly one handling editor. If in doubt, they can send their paper to one of the Managing editors (see the list of Editors) with a mail explaining their query.

Papers submitted to the journal of Groups, Complexity, Cryptology must be written in English, must be related in a wide sense to the topics of the journal, and should not exceed 50 pages. If authors feel that substantially more pages are needed, they should explain why to the handling editor.

LaTeX style

The final version of the papers must be produced using LaTeX and the journal's class file, jgcc.cls.The files instructions.tex and instructions.pdf take the form of a sample article. They contain stylistic requirements and can be used as a template for new articles.

The journal of Groups, Complexity, Cryptology is a community effort. It is run by scientists who devote their time and energy to make this a high quality open access journal that is free of cost for readers as well as for authors. To minimize extra work for the lay-out editors and to ensure smooth and fast publication of accepted articles, authors are asked to strictly adhere to the rules set out in instructions.tex. For the same reason, authors must make their best effort to produce articles written in correct English. 


The handling editor is responsible for the refereeing of each submission. The editor may:

  • accept the paper for publication, possibly subject to minor revision. Authors are requested to prepare a final version within two months, accompanied by a detailed response to the referees' comments.
  • recommend a revision of the paper. This is the case where the editor concludes from the referee reports that the paper deserves publication, but requires the referees to review the revised version. This revised version is handled by the same editor; and it should be accompanied by a detailed response to the referees' comments.
  • reject the paper. 


Once a paper is accepted, the authors share with jGCC the ownership codes of their paper on arXiv or HAL, so the Managing Editors can post the final, accepted version completed with volume number, DOI, etc. The authors retain the full copyright on their paper, under the Creative Commons CC BY 4.0. They commit to not posting a later revised version of their paper without the prior consent of the journal.


The journal of Groups, Complexity, Cryptology publishes only original papers which have not been published previously, nor are being submitted for publication elsewhere. 

Publication of Revised Versions

In exceptional cases, for example if an error is discovered in a paper published by the journal of Groups, Complexity, Cryptology, authors may publish a revised version accompanied by a statement explaining the changes that have been made. Both versions will be available on the journal of Groups, Complexity, Cryptology web site.

Managing Editor Rights

The Managing Editors retain the right to require changes to papers after their acceptance by the handling editor. Such changes normally concern matters of style or format, usually because authors did not follow the stylistic rules of the journal, or because the linguistic quality of the paper requires more work than the editorial team can devote to it.
