Instructions for Authors

    General Requirements. The Journal of Operator Theory endevours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. A manuscript submitted for publication must:

  1. be correct;
  2. be significantly new in a nontrivial sense. A new theorem with an old proof is not publishable;
  3. be of interest to an appreciable number of readers;
  4. be clearly written. The incorrect use of the language is not admissible;
  5. cite correctly prior relevant work related to the subject and indicate the use of the others' ideas.
    Submission. To submit a paper for publication in the Journal of Operator Theory, an author should send two hard paper copies of the manuscript to one of the five Editors. The following information is required: name of Journal for submission, title of paper, author(s) names and official affiliation, mailing address of all authors, e-mail addresses of all authors, corresponding author, telephone and fax numbers. The submission of a paper carries with it the author's assurance that it has not been copyrighted, published, or submitted for publication elsewhere. Manuscripts can be written in English (preferable), French, or German. Preference will be given to manuscripts between 10 and 30 typewritten pages.

    Electronic Submission. Electronic submission is acceptable by all five Editors. To submit a manuscript electronically, an author should send an e-mail message to one of the five Editors with the manuscript attached as a PDF file. The message (which will be considered as the submission letter) should contain the following information: name of journal for submission, title of paper, author(s) names and official affiliation, mailing address of all authors, e-mail addresses of all authors, corresponding author, telephone and fax numbers.

    Style. Authors of papers submitted for publication should strive for expository clarity and good literary style. Typesetting the manuscript using one of the TeX family, one sided and at 12 point, is mostly welcome, but this is not a condition for acceptance. Otherwise, manuscripts should be typed on one side only, double spaced, with generous margins. Footnotes should be avoided. Hand inserted symbols should be well spaced and legible; unusual symbols should be  avoided.  Items required:

  1. The title should be informative. For a longer title a running short title should be indicated.
  2. Authors' names are listed in alphabetical order and formatted as follows: First (Given) Name, Middle Initial(s), Last (Family) Name.
  3. An abstract of at most 8 rows should be included. The abstract should summerise the results of the paper and nothing more. The main purpose of the abstract is to enable the readers to take in the nature and results of the papers quickly and to decide whether they are willing to read the entire paper or not.
  4. A list of keywords should be provided. It has the role of indicating the important topics considered.
  5. The Mathematics Subject Classifications (2000) categories should be included. Their role is to identify accurately the fields of the article.
  6. The first section is usually an introduction. It has the role of presenting the general framework of the paper, historical notes, relevance of the investigation and an outline of the main results. Repetition should be kept to a minimum.
  7. The body of the article should be usually divided in sections.
  8. The results should be distinguished correspondingly as theorems, propositions, lemmas and corollaries. Remarks, definitions, and examples can be used.
  9. Preferable is that all the items to be numbered  within sections: the first figure is the section number, the latter designates the number of the item within the same section.
  10. The beginning and the end of the proofs should be clearly emphasized. If necessary, proofs can be divided in steps. Nested proofs should be avoided as much as possible.
  11. Acknowledgements for grants should be placed before the references.
  12. Items listed as references should be relevant to the subject of the paper. The list of references must be in alphabetical-chronological order. Abbreviations of names of journals and references should follow the standard form established by the Mathematical Reviews.
  13. The authors and their addresses, including the e-mail addresses, if available, should be placed at the end of the manuscript. Authors will be always listed in alphabetical order, unless specifically required (not recommended).
    File Processing. In order to maintain consistency of the style in this journal, all electronic submissions are run through our production system. The printing of the Journal of Operator Theory uses a specially designed style in AMS-LaTeX. Having the TeX source files handy, a lot of work is saved and the editing process is considerably speeded up. Therefore, the authors of the papers accepted for publication are asked to send the corresponding AMS-LaTeX (LaTeX, or the like) files in ASCII format to the Editorial Office in Bucharest, either by e-mail or by using an MS-DOS formatted 1.44MB diskette.

    Figures and Diagrams. Figures and diagrams should be preferably drawn in one of the packages available in AMS-LaTeX; if this is not possible, then they can be embedded as exterior files, necessarily in Encapsulated PostScript (EPS) format and e-mailed as attached files. You should not use the package psfrag; all characters should be contained in the EPS files. Color figures, if provided, will be printed black-and-white only.

    AMS-LaTeX File Processing. It is preferable that papers accepted for publication in the Journal of Operator Theory be prepared in AMS-LaTeX. Even LaTeX2e files are still acceptable, but AMS-TeX and plain TeX files are difficult to rekey. When coding your AMS-LaTeX (or LaTeX2e) file, please bear in mind the following:

  • Use the LaTeX2e and AMS-LaTeX commands and cross-reference capabilities as much as possible. Do not hardcode your own layout, for example by creating your own section headings, theorems and the like, displayed equations, etc.
  • Keep it simple. Do not define macros to create a complicated layout, as these will make the input process complicated.
  • Be consistent. If you use a macro for a phrase, use it throughout.
  • Figures may be inserted in the usual way using an \includegraphics command at the position in the article where they are cited.
If the LaTeX file is suitable, proofs will be produced without rekeying the text.

    File Processing by the Authors Themselves. Authors are encouraged to process their electronic files using the style file of the Journal of Operator Theory, prior to sending these to the Editorial Office in Bucharest but only after acceptance. All necessary files, including instructions and examples, can be downloaded from this site (click on the button Downloads from the left panel), or e-mailed by request.

    Manuscript Alteration. A hard paper copy of a manuscript accepted for publication is sent by the Editor to the Editorial Office in Bucharest. This copy represents the paper  to be published. Subsequent alteration of this manuscript exceeding 5% in volume will be considered as a revision and requires at least a confirmation from the communicating Editor. Alterations of the electronic file (if any), compared to the accepted manuscript, should refer only to typos or small changes of presentation, not exceeding 5% in volume.

    Galley Proofs. For papers with multiple authors it is necessary to indicate to whom the galley proofs should be sent. The designated author should report promptly any change in his/her addresses.

    File Proofreading. There is a variant that might speed considerably up the author's proofreading process, as well as prevent occasional mail hazards. As soon as the processing of the file corresponding to a paper will be accomplished, the proofs may be sent to the designated author by e-mail, as an attached PostScript or PDF file; it is supposed that the author will then e-mail us back a list with his/her corrections and comments. This variant is chosen only if the author indicates to us that he/she can handle postscript files and agrees to use this variant for correcting the galley proofs.

    Modifications During Proofreading. Modifications (that is, deleting and inserting of text, with respect to the accepted manuscript) during proofreading are admitted within 5% of the volume of the accepted manuscript. Out of this range, any modification will be considered as a revision of the manuscript and will require a confirmation from the communicating Editor. A Note Added in Proof of at most two printed pages is accepted and is not considered as a modification.

    Charges. It is the journal policy that there are no page charges for published articles.

    Offprints. An author will receive 70 free offprints of an article published in the Journal of Operator Theory. Joint authors share these 70 copies. An order for additional charged offprints may be placed only before printing, preferably during the proofreading.
