Instructions for authors


Manuscripts should be typeset in English with double spacing by using AMS-LaTex. The authors should use the TMRG style file that has been developed for LaTeX2e standard and can be found at TMRG_style_file_Latex.tex (see also TMRG_style_file_Latex.pdf).

The AOT is an author-prepared journal which means that authors are responsible for the proper formatting of accepted manuscripts by using the style file of the AOT. The authors should carefully take care of the following items in their manuscripts:

Abstract: The abstract should number no more than 200 words and include no reference citations.


2010 Mathematics Subject Classifications: Include only one Primary classification; if applicable, apply at least one Secondary classification. At least one of the Primary or Secondary classifications should be in MSC46 (functional analysis) or MSC47 (operator theory).


Keywords: Provide 3-5 keywords that best describe the subject of the paper.


Authors: Provide full names, mailing addresses, and e-mail addresses for all authors within the paper. Only one author should be the corresponding author.


Figures and supplemental files: Provide all figures and any other supplemental files needed to process the paper.


Typesetting environments: Typeset each theorem, proposition, corollary, lemma, definition, example, etc. in its respective environment, such as \begin{theorem} . . . \end{theorem}.


Margins: A long formula should be broken into two or more lines. Extra line and word spaces in the text should be removed.


Tags (formula numbers): Equations in the text must be labeled by \label{A}. References to them must be typeset using \eqref{A}. Unused tags must be removed. Manual numbering of equations or sections must be avoided.


Acknowledgments: Place acknowledgments, if there are any, near the end of the paper, preceding the references.


References: Use \cite{B} to refer to a specific book/paper in the text. Remove unused 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, for example, [2] or [3, Theorem 4.2].


Abbreviations: Abbreviations of titles of periodicals/books should follow the format used by Mathematical Reviews: see Abbreviations of Names of Serials or MR Lookup.


Citations: The total number of self-citations should be no more than a 0.25 of the total number of references. The total number of references should be at most 1.5 times the number of pages.



The manuscripts must be submitted via

Acknowledgement of the receipt and the notification of the editorial decision on publication will be sent by the system via email. All editorial correspondences should be addressed to the editor-in-chief at


Referee process

Submitted papers must be correct, original, nontrivial, and well written in the scope of journal, and with deep results. If the language used is very poor, then the manuscript will be rejected. A submitted paper will be refereed in the traditional way by at least one referee. AOT tries to make the decision within four months after submission, but this primarily depends on the referees. If you have not received a notice of the decision after four months, kindly send a reminder to the editor in chief by e-mail. If necessary, the corresponding author will be asked to revise the manuscript according to the referee report(s). The editorial board reserves the right to make reasonable modifications to the wording in a manuscript.


Galley proof

The page proofs of each paper will be sent to the corresponding author, who is responsible for checking and approving the article on behalf of all coauthors. A limited number of typographical corrections are anticipated and extensive revisions may be reviewed again.


One volume per year consisting of 4 issues from 2017.





Publication charge

There is no publication or page charge associated with this journal.


By submitting a manuscript, the authors agree that the copyright for their article is transferred to the publisher, if and when, the paper is accepted for publication. The published articles are distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided each paper is properly cited.


Publishing Ethics

AOT is applied for being a member of the Committee on Publication Ethics (COPE).

Publishing Ethics:

Advances in Operator Theory complies with the International Mathematical Union's Committee for Electronic Information Communication (CEIC) Recommendations on Information and Communication: Best Current Practices for Journals (endorsed by the IMU General Assembly 16 August 2010).

The Tusi Mathematical Research Group (TMRG) is obliged to assist the math community in publishing ethics. No paper that has been previously published, that has been copyrighted, or that is being considered for publication elsewhere, should be submitted to the AOT. Nor may a paper that is under consideration by the AOT be submitted elsewhere. By submitting a manuscript, the authors confirm that there is no plagiarism and duplicate submission.
