Authors should submit their papers to the Annual of Sofia University “St. Kliment Ohridski” Faculty of Mathematics and Informatics either by registering at https://annual.uni-sofia.bg/index.php/fmi/ or via e-mail to annuaire@fmi.uni-sofia.bg.
Annual is published in December each year.
All issues of the Annual of Sofia University “St. Kliment Ohridski” Faculty of Mathematics and Informatics since 1991 are available in electronic form at Archives section. All issues from 1944 to 1990 are digitalized and available on the official web page of the Faculty of Mathematics and Informatics at Sofia University.
All manuscripts will be single-blind peer-reviewed by two reviewers – a member of the Editorial board and a reviewer – independent experts in the manuscript subject area. The peer review process is described in the Peer review policy section.
The reviewers’, editors’ and authors’ obligations are presented in the Publication ethics section. All submissions will be reviewed against relevance, originality, significance, soundness, and clarity.
Submission of manuscripts
The Annual is published once a year. A pdf file of the manuscript should be sent to the e-mail address of the Annual annuaire@fmi.uni-sofia.bg or submitted on the journal’s web site https://annual.uni-sofia.bg/index.php/fmi/ . Once received, the manuscript will be subjected to rapid, but thorough review process. If accepted, it is immediately scheduled for the nearest forthcoming issue. No page charge is made.
The submission of a paper implies that it has not been published, or is not under consideration for publication elsewhere. In case it is accepted, it implies as well that the author(s) transfers the copyright to the Faculty of Mathematics and Informatics at the Sofia University “St. Kliment Ohridski”, including the right to adapt the article for use in conjunction with computer systems and programs and also reproduction or publication in machine-readable form and incorporation in retrieval systems. A printable pdf file of the published paper will be available on the journal website.
Instructions for authors
Preferences will be given to papers, not longer than 25 pages, written in English and typeset by means of LATEX or MS Word. MS Word files will be converted to LATEX. Authors are strongly encouraged to use LaTeX template or MS Word template of the journal.

The first page of manuscripts must contain a title, name(s) of the author(s), a short abstract, a list of keywords and appropriate codes according to Mathematics Subject Classification 2020 (MSC2020), see https://msc2020.org/ or 2012 ACM Computing Classification System (CCS), see https://dl.acm.org/ccs . The affiliation(s), including the electronic address, should be given at the end of the manuscript.
Figures have to be inserted in the text near their first reference. The graphic files in any format of the following jpg, png, pdf, eps should be submitted together with the final version of the manuscript after acceptance.
