Scientific Studies and Research Series Mathematics and Informatics (SSRSMI) is committed to publish only original articles which are not considered for publication elsewhere and have not been previously published (excepting the electronic preprints and parts of the academic theses). All the authors of an article jointly accept the responsibility for the submitted manuscript. The articles submitted for publication in SSRSMI are expected to acknowledge the work of other researchers through appropriate references. All the articles are checked for plagiarism. If the ethical standards for publication are not met, or the degree of novelty is low, or the original contribution is not a significant one, then the article will be rejected and the corresponding author(s) will be notified.

The contributed papers should be written in English or French. The title of the paper and the names of the authors are followed by a short abstract, 2 to 6 key-words and phrases and Mathematics Subject Classification numbers. References, including titles of the papers, are numbered, ordered alphabetically according to the authors name, with the abbreviations of the Mathematical Reviews for journals.

The institutional affiliation , mailing address and e-mail address of each author should appear at the end of each manuscript.

Manuscripts prepared for publication should be sent in a PDF format by e-mail, at the e-mail address mmocanu@ub.ro.

After receiving a manuscript, we will send an e-mail message to the correspoinding author.

Contributions to this journal must report original research and will be subjected to review by referees.

Authors receive only one set of proofs for correction. Upon acceptance of the paper, the authors will be asked to send the source file containing the paper, in Tex format, template.tex , as an attachement to an e-mail message.

The editorial board is commited to accept only high-quality papers for publication. All scientific papers submitted to "Scientific Studies and Research. Series Mathematics and Informatics" are peer-reviewed, as follows:

1. Papers should be submitted to the editor-in-chief, by e-mail.
2. Received papers are first analyzed by the editorial board, that can reject those papers that have an improper scientific level or do not fit in the topics of the journal.
3. The papers passing the above step are analyzed by two scientific reviewers, experts in the field of the paper.   The reviewers send to the editor-in-chief a Manuscript evaluation form (report), containing their opinions on the scientific content of the paper and their recommendation on accepting/accepting with corrections/rejecting the paper.
4. The editor-in-chief   send the reports to the corresponding author, in order to modify the paper according to the suggestions of the reviewers.
5. After the revision of the paper, the editor- in-chief checks if all corrections have been made and communicates the decision on the publication to the corresponding author.

Scientific Studies and Research Series Mathematics and Informatics (SSRSMI) is committed to maintaining the highest standards of publication ethics and integrity.
