Guide for Authors

Journal of Approximation Theory
External link http://www.elsevier.com/locate/jat

The Journal of Approximation Theory is devoted to pure and applied approximation theory and related areas. Criteria for publication include novelty, importance, and clarity of presentation.

Submission of Manuscripts

Authors are requested to submit their papers electronically by using online manuscript submission available at External link http://ees.elsevier.com/jat This site will guide authors stepwise through the submission process. Authors can upload their articles as LaTeX, Microsoft (MS) Word, or WordPerfect files. The Elsevier LaTeX package (including detailed instructions for LaTeX preparation) can be obtained from the Quickguide: External link http://www.elsevier.com/latex. It consists of the files: elsart.cls, guidelines for users of elsart, a template file for quick start, and the instruction booklet "Preparing articles with LaTeX". It is also possible to submit an article in PostScript or Adobe Acrobat PDF format, but if the article is accepted, the original source files will be needed. If authors submit word processing files, the system generates an Adobe Acrobat PDF version of the article, which is used for the reviewing process. Authors, reviewers, and editors send and receive all correspondence by e-mail and no paper correspondence is necessary.

Original papers only will be considered. Manuscripts are accepted for review with the understanding that the same work has not been and will not be nor is currently submitted elsewhere, and that its submission for publication has been approved by all of the authors and by the institution where the work was carried out; further, that any person cited as a source of personal communications has approved such citation. Written authorization may be required at the Editor's discretion. Articles and any other material published in the Journal of Approximation Theory represent the opinions of the author(s) and should not be construed to reflect the opinions of the Editor(s) and the Publisher.

Copyright and Permissions

Upon acceptance of an article, authors will be asked to transfer copyright (for more information on copyright, see External link http://www.elsevier.com/authorsrights). This transfer will ensure the widest possible dissemination of information. A letter will be sent to the corresponding author confirming receipt of the manuscript. A form facilitating transfer of copyright will be provided after acceptance.

If material from other copyrighted works is included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted forms for use by authors in these cases: contact Elsevier Global Rights Department, P.O. Box 800, Oxford OX5 1DX, UK; phone: (+44) 1865 843830, fax: (+44) 1865 853333, e-mail: permissions@elsevier.com.

Preparation of Manuscript

Authors are strongly encouraged to use the LaTeX template available on the Elsevier Quickguide at External link http://www.elsevier.com/latex.

Please write your text in good English (American or British usage is accepted, but not a mixture of these). Italics are to be used for expressions of Latin origin, for example, in vivo, et al., per se. Authors who require information about language editing and copyediting services pre- and post-submission please visit External link http://www.elsevier.com/wps/find/authorshome.authors/languagepolishing or contact authorsupport@elsevier.com for more information. Please note Elsevier neither endorses nor takes responsibility for any products, goods or services offered by outside vendors through our services or in any advertising. For more information please refer to our Terms & Conditions External link http://www.elsevier.com/wps/find/termsconditions.cws_home/termsconditions.

Manuscripts should be double-spaced throughout. Number all pages consecutively and organize the paper as follows.

Title page (page 1). This page should contain the article title, authors' names and complete affiliations, footnotes to the title, and the address for manuscript correspondence (including e-mail address and telephone and fax number).

Abstract (page 2). The abstract must be a single paragraph that summarizes the main findings of the paper in less than 150 words. After the abstract a list of up to 10 keywords that will be useful for indexing or searching must be included.

Footnotes. In text, footnotes should be avoided. If absolutely necessary, identify them by superscript Arabic numerals in order of their appearance and type them together on a separate page, double-spaced.

Equations. All equations should be typewritten and the numbers for displayed equations should be placed in parentheses at the right margin. References to equations should use the form ''Eq. (3)'' or simply ''(3).''

References to the literature should be cited by Arabic numerals between brackets as [1], [1,2], [1, Theorem 1.5] in the text and listed in numerical order at the end. Please note the following examples:

[1] R.Q. Jia, J.J. Lei, Approximation by multi-integer translates of functions having global support, J. Approx. Theory 72 (1993) 2-23.

[2] A.G. Ramm, Multidimensional Inverse Scattering Problems, Longman/Wiley, New York, 1992.

[3] Y. You, Polynomial solutions of BKP hierarchy and projective representation of symmetric groups, in: Advanced Series in Mathematical Physics, Vol. 17, World Science, Singapore, 1989.

For unpublished lectures or symposia, include the title of the paper, name of the sponsoring society in full, and the date. For journal names, follow ''Abbreviations of Names of Serials reviewed in Mathematical Reviews'' (American Mathematical Society, 1995). When in doubt about employing certain abbreviations, use clarity as a guide.

Tables. Number tables consecutively with Arabic numerals in order of appearance in the text. Type each table double-spaced on a separate page with a short descriptive title directly above and essential footnotes below.

Figures. Number figures with Arabic numerals. Digital artwork of at least 300 dpi resolution is accepted in EPS or TIFF format. Please visit our Web site at External link http://www.elsevier.com/artwork for detailed instructions on preparing electronic artwork. Type all legends consecutively on a separate page.

Color art is permissible, but the extra printing costs will be charged to the author. However, if together with your accepted article you submit usable color figures, then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. For further information on the preparation of electronic artwork, please see External link http://www.elsevier.com/artwork

Please note: Because of technical complications that can arise in converting color figures to "gray scale" (for the printed version should you not opt for color in print), please submit in addition usable black-and-white files corresponding to all the color illustrations.

Preparation of Supplementary Material

Elsevier now accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer additional possibilities for publishing supporting applications, movies, animation sequences, high-resolution images, background datasets, sound clips, and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect (http://www.sciencedirect.com). To ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. Please note, however, that supplementary material will not appear in the printed journal. For more detailed instructions, please visit Elsevier?s Quickguide at External link http://www.elsevier.com and then click on "Multimedia files."

Proofs

PDF proofs will be sent by e-mail to the corresponding author. Corrections should be returned promptly.

Author Inquiries

For inquiries relating to the submission of articles (including electronic submission where available) please visit Elsevier's Quickguide at External link http://www.elsevier.com. Elsevier's Quickguide also provides the facility to track accepted articles and set up e-mail alerts to inform you of when an article's status has changed, as well as detailed artwork guidelines, copyright information, frequently asked questions, and more. Contact details for questions arising after acceptance of an article, especially those relating to proofs, are provided after registration of an article for publication.
