Author Guidelines

Authors should remove identifying information following the recommendations below and submit a PDF copy of their manuscript via the EditFlow submission page.


Combinatorial Theory uses a doubly anonymous reviewing process. This means that referees will not be told the names of the authors of the papers they review, and authors will not be told the names of the referees who review their papers. The journal asks referees not to do additional research to identify the authors.

The philosophy behind doubly anonymous refereeing is to reduce the effect of initial impressions and biases that may come from knowing the identity of authors.Our goal is to work together as a combinatorics community to select the most impactful, interesting, and well written mathematical papers within the scope of Combinatorial Theory.

Authors may post their papers on the arXiv or elsewhere on the internet while they are being reviewed in Combinatorial Theory.

Before submitting your manuscript, prepare your submission according to the following checklist. Papers not conforming to these recommendations will be returned to authors with a request to “scrub” identifying information.

  • Search and remove the authors’ names, grant numbers, and affiliations and other identifying information from the paper; in particular from the front matter, back matter, introduction, and page headers.

  • Remove the acknowledgements section.

  • Remove phrases and indications that particular citations have authors in common with those of your paper. Pay special attention to the abstract and introduction. (For example, replace “In [1], the first author proved…” with “In [1], it was proved…”)

In addition, the manuscript should be spell checked and grammar checked.

For questions regarding submissions to Combinatorial Theory, authors may contact or the confirmation e-mail of a submission.

Final version

Manuscripts accepted for publication must be prepared using the CT LaTeX style file ct.sty in the same manner as ct-sample.tex to produce output similar to ct-sample.pdf. In particular, LaTeX should run on your paper without reporting errors such as overfull hboxes.

We encourage the use of BibTeX with one of \bibliographystyle{amsalpha} or \bibliographystyle{amsplain} to format the bibliography entries.

Upload a PDF of your paper, and upload all source files as "supplementary files” bundled into a single zip file.

Here is a list of undesirable common typesetting issues that we ask you to avoid:

  • Using ellipses … instead of \ldots, \dots, \cdots.
  • No spaces before a comma or full-stop/period.
  • ASCII characters that usually arise from diacritics. Do not use á, use \’{a}.
  • Overfulls.
