Preparation of the manuscript

Submission formats

Manuscripts must be submitted to the submission platform simultaneously in two formats, with line numbering: LaTeX and PDF.

If you have missed files in your initial submission:

If the missing files are numerous and/or significantly change the content of the submission, please abandon the initial submission and make a new submission;
Otherwise, please open a discussion in OJS with the editor, attaching the file(s) and asking the editor to add them.

General information

Please use preferably TeX, Plain Tex or LaTeX, or possibly AMS-Tex or TeXTURE. Macros should be provided with TEX files (avoid DVI format). The bibliographic references should be stored in a bibtex file.

Authors are strongly encouraged to use the journal's LaTeX class file and bibtex style, but amsart or smfart classes, as well as amsplain and smfplain styles are accepted.

Composition Recommendations

Language

Articles can be written in French or in English.

Any article received in a poor-quality English or French will be immediately rejected. Please feel free to use automatic proofreaders (e.g. DeepL) if necessary.

If neither English nor French is your native language, please have your manuscript proofread by a native speaker or use a professional language editing service.

For a better dissemination of your article, it is recommended to provide an abstract in the language of submission (max. 100 words), as well as a translated title and abstract (in French if your article is written in English, in English if it is written in French).

Mandatory information

Manuscripts should include, in the following order:

1) the title: it should be short, but explicit;

2) names of all authors: please include full first names, and include an asterisk after the name of the author to whom correspondence and proofs should be sent;

3) the complete professional addresses of all authors (including email address): to be entered during step 3 "Enter metadata" of the online submission procedure;

4) the text of the article: it must be typed, double-spaced, and each page must be numbered. Organize your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in the section numbering) and have a brief title. Also use this numbering for internal references: do not just refer to the "text";

5) references, captions, tables and illustrations.

Optional information

You can include in your manuscript:

Bilingual or abridged version: it is possible to submit a fully bilingual French/English article, or to accompany the text of the article with an abridged version (in French if the article is written in English, in English if it is written in French). This abridged version (no length limit) is distinct from the abstract (100 words max.).
Acknowledgements:
- List here those who provided assistance during the research (e.g., language assistance, help with writing or proofreading the article, etc.).
- Please do not include these acknowledgements on the title page, as a footnote to the title or otherwise, but collect them in a separate section at the end of the article, before the references.
Dedication: a one-sentence dedication of the article can be a separate paragraph after the "Acknowledgements" section.
Funding sources:
- Please list your funding sources on this template, which conforms to the requirements of major funders:
  Funding: This project has received funding from the European Research Council (ERC) under the European Union’s Horizon Europe research and innovation programme (Grant agreement No. [yyyy]) and the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz].
- It is not necessary to include a detailed description of the program or type of grant or award. When funding is from a block grant or other resources provided to a university, college, or other research institution, please indicate the name of the institute or organization that provided the funding.
Appendices:
- If there is more than one appendix, please identify them by letter (A, B, etc.).
- Formulas and equations in the appendices should be numbered separately: (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. The same applies to tables and figures: Table A.1; Fig. A.1, etc.
Footnotes:
- Footnotes should be used sparingly. Number them consecutively throughout the article.
- Do not include footnotes in the reference list.

Length

There is no page limit for articles submitted to the Comptes Rendus Mathématique. However, the maximum recommended length for a manuscript is about 50,000 characters including spaces (an illustration counts for 1,200 characters on average), which is equivalent to about 10 pages.

References

Please ensure that your bibliographic references:

Are numbered in alphabetical order;
Are presented between square brackets in the text as in the final bibliography;
Mention all the authors of each reference (name and initials of the first names);
Cite journal titles in their abbreviated form recognized by international rules, including the title;
Include the first and last pages of publication.

NB: Your bibliographic references will be reformatted by our editorial teams, so the examples above are not identical to the references you might find in our already published articles.

Illustrations

Please:

Provide your illustrations as separate files, please choose image formats (JPEG, PNG, EPS, Adobe Illustrator... - note that EPS is not suitable for illustrations containing text) in the best possible resolution (enlarged to 400%, your illustrations must not become blurred or pixelated);
Label all your illustrations as figures and/or diagrams;
Number your illustrations in Arabic numerals, in the order they appear in the article;
Use consistent units and symbols between all illustrations and with the text;
Use consistent lettering and dimensions for all original illustrations;
Use Helvetica as the preferred font (if not available, use Arial, Courier, Times New Roman, Symbol or similar fonts) for text appearing in figures;
Check that your illustrations will be adapted to a resizing on 75 mm width (single column), 160 mm for illustrations straddling two columns;
Make sure that none of your illustrations exceed A4 size (210 x 297 mm);
Ensure that photographs and halftones have good contrast;
Make sure that the characters integrated in your illustrations remain legible even after reducing the size of the illustrations by 70%;
Integrate the fonts used directly into your illustrations if the design software you use allows it;
Provide a caption for each of your illustrations;
Check that your illustrations are all cited in the body of the text.

Please use only royalty-free illustrations in your manuscript. If you use a copyrighted illustration, please obtain permission from the copyright holders to reuse it under a Creative Commons CC BY 4.0 license (see below).

Other recommendations

Please:

Present mathematical equations clearly;
Do not start a sentence with a mathematical formula;
Use international units;
Define in the text any non-standard conventions or abbreviations when first used;
Explain in the text any non-standard symbols.

Open data policy

Source files

Authors wishing to publish in Comptes Rendus Mathématique are requested to provide all the files necessary for the formatting of their article in the most interoperable formats possible, in order to facilitate the work of the editors.

In order to encourage the free circulation of scientific knowledge, authors are strongly encouraged to accept the publication by Comptes Rendus Mathématique of these source files, together with the editorialized files. The dissemination of figures, in particular, especially when made available in an interoperable format and in high quality resolution, is a strong commitment to more open and robust science.

Underlying data

Research data includes all "materials in digital form, other than scientific publications, that are collected or produced in the course of scientific research activities and used as evidence in the research process, or that are commonly accepted by the scientific community as necessary to validate research findings and results" (source: EU Directive 2019/1024).

Authors wishing to publish in the Comptes Rendus Mathématique are encouraged to make all data related to the research work they describe in their manuscripts, and in particular the data directly underlying the submitted articles, freely available.

To do so, Comptes Rendus Mathématique strongly recommends that authors deposit their data in warehouses, i.e. databases specifically dedicated to the permanent preservation, enrichment and valorization of the materials they host. Datasets deposited in repositories are scientific productions that can be cited (in particular when they have a permanent identifier such as DOI), in the same way as a traditional publication.

It is recommended that authors release their data without embargo or after the shortest possible delay, in a way that allows their reuse, with an explicit link between the data and the underlying publication (reciprocal mention of the DOI). The journal encourages the provision of data under open licenses that allow their free reuse. Authors must use the licenses recommended by the repository where the data were deposited.

Reviewers of submitted articles may at any time request from authors the data underlying the results described. Failure to provide this data will result in the rejection of the submission.

NB: Research data should be as open as possible, but as closed as necessary. The Academy of Sciences and the editorial team of Comptes Rendus Mathématique cannot be held responsible for any failure to respect the rights associated with the exploitation or dissemination of the data underlying the articles published by the journal. Authors are invited to inquire about any intellectual or industrial property issues that may arise with their data.

Data Repositories

To select a trusted repository appropriate for your data type or disciplinary area, consult the re3data directory. Check that the chosen repository meets quality criteria.

We should also mention Zenodo, a multidisciplinary data warehouse, supported by CERN and the European Commission. The data deposit is not moderated.

Supplementary materials

Authors who wish to publish in the Comptes Rendus Mathématique may attach to the full text of their submission additional files or material, independent of the body of the article but essential to its understanding. As this material is subject to the peer review process, it must be included and clearly marked as "Supporting Information for Electronic Publication" when the article is submitted. To ensure that your material is directly usable, please make sure that each file does not exceed 50 MB.

However, for reasons of technical constraints, valuation, preservation and reuse, authors are strongly advised to deposit this additional material in dedicated repositories, rather than publishing it as an appendix to the articles.

Reuse of articles in their submitted and accepted versions

Submitted version (author's manuscript or preprint): any author who wishes to publish in Comptes Rendus Mathématique is authorized to pre-publish his manuscript on a pre-publication server such as a rXiv, in an open archive such as HAL, or on any other website such as a laboratory website. The manuscript must be clearly identified as not yet peer-reviewed or accepted for publication, and not containing any modifications requested later.

If the author's manuscript is subsequently accepted for publication and then published by Comptes Rendus Mathématique, the authors must indicate these changes in editorial status, provide a link to the journal and include in the manuscript record the DOI assigned to the final published version.

Accepted version (accepted author manuscript or postprint): any author whose manuscript has been accepted for publication in Comptes Rendus Mathématique may publish the final version of his or her unedited text on a pre-publication server such as a rXiv, in an open archive such as HAL, or on any other website such as a laboratory website. The manuscript must be clearly identified as having been peer-reviewed, corrected following their requests and accepted in principle by the journal, with a link to the journal's website.

After publication by the Comptes Rendus Mathématique, the article description should be modified to include the final DOI assigned to the final published version.

Published version (PDF editor or version of records): the CC BY 4.0 license under which the articles of Comptes Rendus Mathématique are distributed authorizes its authors to deposit the published version of their work in an open archive such as HAL, or on any other website such as a laboratory website, provided that the DOI of the published article is included in the article's descriptive notice.

NB : for a deposit in HAL, you can select the option "I have checked that this publisher belongs to those which authorize the submission of the “file editors” on an open archive".

Choose a platform of self-archiving

To choose the preprint server, open archive or portal best suited to disseminate your author manuscripts, feel free to consult the Open Directory of Open Access Repositories (OpenDOAR), a service of JISC.
