**Manuscripts** in the form of PDF files should be **submitted** here. **Submission** of a manuscript implies that the work described has not been published before (except in the form of a preprint), that it is not under consideration for publication elsewhere, and that it will not be submitted elsewhere unless it has been rejected by the editors of Fundamenta Mathematicae.

For joint papers, Fundamenta Mathematicae maintains correspondence with only one author. You may contact us through the editorial system or by email.

An **abstract **in English of not more than 200 words, the **AMS Mathematics Subject Classification** and a list of** keywords** and phrases are required.

**On acceptance of the paper** the corresponding author will be asked to transmit the source file, and **on the proof stage** to sign the copyright transfer agreement.

The publisher strongly encourages preparing the manuscript in any version of TeX. Recommended **format**: 12-point type (including references), text width 13.5 cm.

**Template files**

The amsart style: IMPAN-amsart.tex, IMPAN-amsart.pdf

The article style: IMPAN-article.tex, IMPAN-article.pdf

**Figures** must be prepared in electronic form, suitable for direct reproduction. The use of very thin lines should be avoided.

**References** should be arranged in alphabetical order and styled according to the examples given below. Abbreviations of journal names should follow Mathematical Reviews.

Examples:

**Affiliations** of all authors should be given.

PDF **proofs** will be e-mailed to the corresponding author.

The **Online First** version of the article will be sent to the author and published on the journal's web site before the article is assigned to an issue. This version will be freely downloadable for everybody. The author is allowed to post the “Online First” version to his/her personal web site and to any other archives.

When the paper is assigned to an issue, the **final print file** with all publication data included will also be sent to the author. The latter file will be for the author's personal use only and should not appear on any web site other than IMPAN’s.

Authors retain the right to distribute their author accepted manuscript under a CC-BY license.

The article can also be published in **Open Access** (under CC-BY license) upon paying a fee of 400 euros.

The decision should be communicated at the proof stage; the appropriate invoice will then be sent to the author.
