Guide for Authors

Preparation of manuscripts:

Manuscripts should be typeset in English with double spacing by using AMS-LaTeX (Word files (*.doc) are not accepted). In the case of acceptance, the author should prepare the paper by using the style file of the LaTeX IJNAA package.

While you are preparing your paper for submission, please take care of the following:

  • Submissions must be more than 6 pages based on the IJNAA style.
  • The abstract should not exceed 250 words.
  • The (full name) authors should include as footnotes for the first page,
  • Keywords and MSC codes must accompany all articles. A list of the subject classifications can be accessed or searched online in the Annual Index of Mathematical Reviews.
  • Other footnotes may also be included on the first page about supporting grants, presentations, etc.
  • A long formula should be broken into two or more lines. Empty spaces in the text should be removed.
  • Figures must be eps file or jpg file more than 300dpi resolution.
  • Acknowledgement should be at the end of the paper but preceding the references.
  • References should be listed in alphabetical order according to the surnames of the first author at the end of the paper and should be cited in the text as, e.g., [2] or [2; Theorem 3], etc. Use cite{B} to refer to a specific book/paper B in the text. Remove unused references. 
  • References should be given in the following format:

i)  to articles in periodicals or collections - author, the title of the article, the title of the periodical (collection), volume, year, pagination;

ii) to books - author, title, publisher, location, year of publication.

Abbreviations of titles of periodicals and collections should be given following Mathematical Reviews at serials.pdf (

We strongly prefer to receive manuscripts via our online submission system. Using this system, authors can upload manuscript files (text, figures and supplementary information, including video) directly to our office and check on the status of their manuscripts during the review process. In addition, reviewers can access the manuscripts (in a highly secure fashion that maintains referee anonymity) over a direct internet link, which speeds the review process.

The submission should include the original source (including all style files and figures) and a PDF version of the compiled output.


Revisions, including manuscripts submitted after a presubmission inquiry, should be uploaded via the link provided in the editor's decision letter. Please do not submit revisions as new manuscripts.

The number of submissions: The IJNAA is recently receiving a huge number of submissions. IJNAA does not accept more than one submission at the time for the refereeing procedure.

IMPORTANT! Please note that not more than 2 papers per calendar year, per author and co-author, can be submitted to the International Journal of Nonlinear Analysis and Applications.



A submitted paper will be refereed in the traditional way by at least two referees. Any member of the editorial board will try to make the decision within 3 months after submission. If necessary, the author(s) would be asked to revise the manuscript according to the referees reports. The editorial board reserves the right to make reasonable modifications in wording.



Submission of a manuscript implies that the work described has not been published before (except in the form of an abstract or as part of a published lecture, review, or thesis); that it is not under consideration for publication elsewhere, that its publication has been approved by all co-authors if any, as well as (tacitly or explicitly) by the responsible authorities at the institution where the work is carried out.

Publishing Ethics:

IJNAA is committed to maintaining high standards through a rigorous peer-review together with strict ethical policies. Any infringements of professional ethical codes, such as plagiarism, fraudulent use of data, bogus claims of authorship, should be taken very seriously by the editors with zero tolerance. IJNAA follows the Code of Conduct ( of the Committee on Publication Ethics (COPE) ( and follows the COPE Flowcharts ( for Resolving Cases of Suspected Misconduct.
