Instruction for Authors: The manuscript should be prepared using LaTeX processing system, basic font 12pt size. The papers must be written in good English and typed in frames 14*21.6 cm (margins 3.5 cm on left and right and 4 cm on top and bottom) on A4-format white paper or American format paper.
Title Page: Provide the following data on the title page (in the order given).
Title. Titles should be concise and informative. Titles are often used in information retrieval systems. Avoid abbreviations and formulae where possible.
Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors’ affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author’s name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.
Corresponding author. Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication, also post-publication.

Abstract: A concise and factual abstract is required (maximum length 150 words). The abstract should state briefly the purpose of the research, the principal results and major conclutions. An abstract is often presented separate from the article, so it must be able to stand alone.
Keywords: Immediately after the abstract, provide a maximum of 6 keywords, using British spelling and avoiding general and plural terms and multiple concepts ( avoid, for example, ‘and’, ‘of’ ). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
AMS Mathematics Subject Classification followed by keywords.
References: Responsibility for the accuracy of bibliographic citations lies entirely with the authors.
Citations in the text. Please ensure that every references cited in the text is also present in the reference list (vice versa). Any references cited in the abstract must be given in full. Citation of a reference as ‘in press’ implies that the item has been accepted for publication.
List. Number the references (number in square brackets) in alphab
etical order. Examples:
Reference to a journal publication:
[1] A. Mostowski, On computable sequences, Fund. Math. 44 (1957) 37-51.
Reference to a book:
[2] W. Strunk Jr., E.B. White, The Elements of Style, Third ed., Macmillan, New York, 1979.
Reference to a chapter in an edited book:
[3] G.R. Mettam, L.B. Adams, How to prepare an electronic version of your article, in: B.S. Jones, R.Z. Smith (Eds.), Introduction to the Electronic Age, E-Publishing Inc., New Yourk, 1999, pp. 281-304.
For an unpublished paper:

Submissions of articles: Authors should submit their articles electronically to the Editor-in-Chief or to an editorial board member of choice, as the area of research of a submission is similar to the board member’s area.
An electronic (PDF) file is generated and the reviewing process is carried out using that PDF. The PDF file you have submitted is sufficient for review purposes only. If your paper is accepted for publication you will be asked to upload the file in the LaTeX format. In exceptional cases, where electronic submission is impossible, authors can send three copies of their articles.
Authors are requested to send the names and addresses of three suggested referees with their submission. The referees should present at least two regions of the world.
