Instructions for authors

Submission of manuscripts. The Annual is published once a year. No deadline exists. Once received by the editors, the manuscript will be subjected to rapid, but  thorough review process. If accepted, it is immediately scheduled for the nearest forth coming issue. No page charge is made. The author(s) will be provided with a free of charge printable pdf file of their published paper. 
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 copy right to the Faculty of Mathematics and Informatics at the “St. Kliment Ohridski” University of Sofia, 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. 
Instructions to Contributors. Preferences will be given to papers, not longer than 25 pages, written in English and type set by means of a TEX system. A simple specimen file, exposing in detail the instruction for preparation of  the manuscripts, is available upon request from the electronic address of the Editorial Board. 
Manuscripts should be submitted for editorial consideration in pdf-format by e-mail to annuaire@fmi.uni-sofia.bg. Upon acceptance of the paper, the authors will be asked to send the text of the papers in .tex format and the appropriate graphic files (preferably in .eps format). 
The manuscripts should be prepared for publication in accordance with the instructions, given below. The first page of manuscripts must contain a title, name(s) of the author(s), a short abstract, a list of key words and the appropriate 2010 MSC codes (primary and secondary, if necessary). The affiliation(s), including the electronic address,  should be given at the end of the manuscripts. 
Figures have to be inserted in the text near their first reference. If the author cannot supply and/or incorporate the graphic files, drawings (in black ink and on a good quality paper) should be enclosed separately. If photographs are to be used, only black and white ones are acceptable. 
Tables should be inserted in the text as close to the point of reference as possible.
Some space should be left above and below the table.
Footnotes, which should be kept to a minimum and should be brief, must be numbered consecutively.
References must be cited in the text in square brackets, like [3], or [5, 7], or [11, p. 123], or [16, Ch. 2.12]. They have to be numbered either in the order they appear in the text or alphabetically. Examples (please note order, style and punctuation):
