Authors who wish to have their manuscript handled by a specific member of the Editorial Board should so notify the Editorial Office at the time of submission.
How to Submit an Article
Submitting a paper to the journal can be performed in two easy ways:
Please indicate in your submission if your paper is intended for a specific special issue of SIGMA.
If within two working days you have not received a confirmation that we have received your paper, please resend it to our alternative address firstname.lastname@example.org
The length of an article is not limited.
The average time of the paper processing, from submission of the paper to appearing of the paper on the journal's web site is 2-3 months, but this essentially depends on the subject and length of the article, so in some cases this time can be longer.
The papers are considered for publication if they have not been published previously and are not submitted for publication elsewhere.
Paper Evaluation Criteria
SIGMA has two article styles: regular article and review article.
Manuscripts submitted as regular articles are expected to be
Review articles are welcome too.
Review articles are critical evaluations of material that has already
been published. By organizing, integrating and evaluating previously
published material, the author of a review article considers the
progress of current research toward clarifying a problem. In a sense,
a review article is tutorial in that the author
Refereeing Papers for SIGMA
All the papers submitted to SIGMA are sent for refereeing to 2-3 experts in the specific areas for evaluation according to the above criteria. These referees can either review the papers themselves or recommend other referee(s).
To ensure comprehensive refereeing and to avoid conflicts of interest we choose the referees having in mind:
We strive to ensure adequate refereeing and selection process. At the moment around 50 percent of the submitted papers are declined, most of the accepted papers have been corrected in accordance with referees' recommendations.
Our policy is to send all the referee reports to the authors as (i) they are written by experts; (ii) and we believe that people need to know alternative opinions on their research. We believe that a constructive referee report is more beneficial for research than just support of the paper that may be improved.
On the other side, we welcome constructive and substantial referee reports (we point out once more that we guarantee anonymity of the referees' identity).
We monitor any possibilities for conflict of interest at selection of the referees, but ask to inform us if such conflict arises.
Please contact the Editors email@example.com for any questions about the editorial process and our refereeing policy.
Special thematic issues in SIGMA
SIGMA welcomes proposals from potential Guest Editors for special thematic issues of the journal, in particular conference/workshop proceedings, issues for anniversaries, etc.
We would like to stress that all papers in the special issues should be original: they should not be simply reviews of authors' own work that is already published elsewhere. Publication will be done only on the results of the peer review according to regular refereeing rules of SIGMA (see the items above).
If you have any ideas for special issue in SIGMA, please contact us firstname.lastname@example.org for further consideration.
SIGMA is arXiv overlay
That means that all published articles in the journal have been contributed or will be contributed to the arXiv. In addition, SIGMA web site has hyperlinks to arXiv copies.
You can also search or browse SIGMA articles within the arXiv, for example by following this link. As a consequence of the overlay arrangement, SIGMA shares the commitment of the arXiv itself to remain permanently and freely available on the Internet.
If a paper accepted for publication is already in the arXiv, the author should give to the Editors both the paper number and the password so that we can replace it with the typeset version.
The authors retain ownership of the copyright with respect to their papers published in SIGMA under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
