About Journal of Physics A: Mathematical and Theoretical

Research papers published in Journal of Physics A: Mathematical and Theoretical™ are categorised into one of six subject sections, defined below. To be acceptable for publication in the journal, papers must make significant, original and correct contributions to one or more of the topics within these sections. Mathematical papers should be clearly motivated by actual or potential application to physical phenomena. Algorithmic papers are encouraged and should contain clear physical background and theoretical motivations.

Journal of Physics A: Mathematical and Theoretical welcomes submissions of the following article types:

• Papers: reports of high-quality original research with conclusions representing a significant advance in the field; usually approximately 10000 words (18 journal pages).
• Letters: outstanding concise articles, reporting important, new and timely developments. These articles should be deserving of priority review, and you are required to upload a justification statement along with your submission. Letters should not exceed nine pages in length or 6500 words.
• Special issue articles: articles which will form a special collection of papers on a specific theme. When asked to select ‘Article Type’ on the submission system, please select ‘Special Issue Article’. Then select the special issue you’re submitting to in the drop-down box that appears.
• Topical reviews: written by leading researchers in their fields, these articles present the background to and overview of a particular field and the current state of the art. Topical review articles are normally invited by the Editorial Board.
• Comments: comment or criticism on work previously published in the journal. These are where possible published with an associated reply. Comments should be timely and should have a direct bearing on the significance of the results in the paper being commented on.

For example, they may:

1. point out and/or correct a significant error or misinterpretation in the results.
2. significantly extend or generalise a result of the paper in some way.
3. point out relevant prior literature that significantly affects the novelty or priority of the results.
