Information For Authors

Aims and scope
Journal of Numerical Analysis and Approximation Theory
publishes, since 1972, original papers in all areas of Numerical Analysis and Approximation Theory. It is a single-blind peer-reviewed journal. It considers for publication only papers written in English. There are no publication fees. For more infomation, see About the Journal.

Peer review process
Submitted manuscripts are first analyzed by the editors-in-chief and then assigned to an editor, provided they are a good fit to the scope of the journal. The editor invites at least two external reviewers with expertise in the addressed topics to write anonymous review reports, in a period of 6-8 weeks typically. The authors are then informed about the editorial decision (acceptance, minor revisions, major revisions or rejection).

For accepted manuscripts, the average time from submission to publication is around 20 weeks.

The entire peer review process is done online on the journal's website using the platform and workflow of Open Journal System.

How to submit

Authors should first check the Submission Guidelines and the Ethics Statements.

Authors need to register with the journal prior to submitting or, if already registered, can simply log in and begin the five-step process.

In the following situations, the authors are asked to create a public profile (e.g.,,,,, etc):
- they have registered to JNAAT not using an institutional e-mail address,
- they do not have a public research profile (homepage, etc.) which contains their CV and list of papers,

The Editorial Board continuously aims to raise the standards of the Journal.

As a general rule, the results obtained in the submitted manuscripts should be supported by examples showing their usefulness.

Topics such as inequalities are accepted if the authors provide applications of the obtained results.

Papers dealing with iterative methods in Rn, accompanied by numerical applications, are preferred to settings in R or abstract spaces (with no concrete applications indicated).

Other rules
Submissions: authors should normally not have more than one pending submission.

Paper length: the papers should have reasonable length according to the topic they address. Authors may choose to post additional figures, tables, results on specific sites (arxiv, etc.).

Artwork. For the best quality paper, it is highly recommended that the authors submit the artwork – photographs, line drawings, etc. – in an electronic format. The published paper will directly reflect the quality of the artwork provided.
