A half-century ago enumerative combinatorics was considered to be mostly a collection of isolated results and methods, mainly originating with Euler. Since then enumerative combinatorics has been transformed into a rich and important research area in mathematics, partly due to its deep connections with other fields of research. The pioneering work of Stanley, especially the two-volume Enumerative Combinatorics, and the book of Flajolet and Sedgewick on Analytic Combinatorics (also, see the Handbook of Enumerative Combinatorics by Bóna and Combinatorial Enumeration by Goulden and Jackson), helped to shape and popularize the subject. Inspired in particular by these books, and more generally by the many fine papers in the subject, we introduce this Journal, Enumerative Combinatorics and Applications.

Enumerative Combinatorics and Applications (ECA) is a fully-refereed scientific electronic journal with very high standards, devoted to the publication of research articles of the highest quality. Therefore, the journal will consider only submissions that contain new insights/ideas/methods/concepts/bijections/applications related to enumeration. The journal covers research from the field of Enumerative Combinatorics as well as research resulting from the rich interplay between enumerations, applications, and other branches of mathematics and science.

The scope of ECA includes enumerative aspects of combinatorial structures and their connections to various areas of mathematics (linear algebra, probability theory, complex analysis, commutative algebra, representation theory, algebraic geometry, algebraic topology), physics, chemistry, computer science, etc. ECA publishes high quality full papers, reviews, surveys, historical papers and biographies of mathematicians. Our main objective is to help amplify the trend of high quality research in enumerative combinatorics by providing a medium dedicated to this exciting field of mathematics and making it publicly available and free of charge to all researchers across the globe.

The Abbreviation of the journal’s title is “Enumer. Combin. Appl.”.

Submission of Manuscript

Manuscripts should be written in English, prepared in LaTeX, and must be submitted as a PDF file in an email attachment to Editor-in-chief: tmansour@univ.haifa.ac.il

Within a week you will receive acknowledgment that your submission has been received.

Submitted manuscripts to ECA will be refereed according to the highest standards. The median time from submission to publication is 6 months. Thus, we ask kindly not to send questions about your manuscript if it has been under consideration for less than 6 months.

After a manuscript is accepted and the final version of the accepted paper is received, it will be published within a few days.

Notes: If your file is larger than 8 MB, contact the Editor-in-chief. Also, in case you did not receive an acknowledgment within a week, then again contact the Editor-in-chief.

When submitting a manuscript, the (corresponding) author, should make sure that the manuscript contains:
(1) Title of the manuscript. The title should be concise and indicate as clearly as possible the subject of the manuscript.
(2) Author names and affiliations. The affiliation should include the postal address, country, and email address of each author.
(3) Abstract. The abstract should describe the problem studied and the main results. It should be concise, informative, and self-contained. It should not contain equation numbers, citations, or references.
(4) Keywords. Specify 2 to 5 keywords.
(5) Mathematics Subject Classification. Include one or more Math. Subj. Class. codes - see https://mathscinet.ams.org/mathscinet/msc/msc2020.html

By submitting the manuscript, the authors confirm that:
- The manuscript has not been previously published.
- The manuscript is not under consideration elsewhere, nor will it be submitted for publication elsewhere while it is being handled by EAC.
- If the manuscript is accepted by ECA, then it will not be published elsewhere.
- The submission file is in PDF document file format.

Upon acceptance of the paper author/s will provide the document in the LaTeX style provided by ECA. The final version Manuscripts accepted for publication must be prepared in LaTeX according to the ECA format example.tex. The LaTex version of the paper should be executed without errors. When submitting the LaTex version of the paper, please send also all ‘supplementary files’. The recommended format for image files is PDF, but EPS format is also acceptable. Regarding references, authors should use the abbreviations of the journals’ names, provided by MathSciNet. Also, make sure that all your references are carefully formatted following the examples provided in the sample file.

In addition to the above, the authors should pay attention to the following matters: When submitting a manuscript, the corresponding author may suggest some potential referees, who have not coauthored with them during the last 5 years. The editorial office may or may not use such suggestions.
