Submit one copy of the manuscript, together with an electronic version (preferably a pdf file), if available. Authors of accepted papers will be asked to provide a LATEX file of the paper, so please bear this in mind when preparing the paper for submission. Manuscripts should be double-spaced throughout on one side of 8.5 x 11-inch (21.3 x 27.5-cm) or A4 white paper. Number all pages consecutively and organize the paper as follows (see sample paper)
Title page 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 The abstract should 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 5 keywords that will be useful for indexing or searching should be included. Then recent Mathematics Subject Classification codes (MSC2000) should also be included.
Footnotes In text, footnotes should be avoided.
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. Authors should submit complex tables as camera-ready copy.
Figures Figures should be in a finished form suitable for publication. Number figures with Arabic numerals, and indicate the top and the authors on the back of each figure. Lettering on drawings should be professional quality or generated by high-resolution computer graphics and must be large enough to withstand appropriate reduction for publication. Figures should not be embedded in the text. Digital artwork of at least 300 dpi resolution is accepted in EPS format.
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 must be quoted in the text in square brackets, i.e., [1], [1,2], or [2, p. 51], and grouped at the end of the paper in numerical order of appearance. Abbreviations of journal titles should follow those given in the World List of Scientific Periodicals (latest edition). References should be arranged as follows:
Journal articles: 1. O. Rojo and R. Soto, New conditions for the additive inverse eigenvalue problem for matrices, Computers Math. Applic. 23 (11) (1992), 41-46.
Papers in a collection: 2. G.M. Nielson, Coordinate free scattered data interpolations, In Topics in Multivariate Approximation, (Edited by L.L. Schumaker et al.), pp. 175-184, Academic Press, New York, (1987).
Books: 3. R.A. Adams, Sobolev Spaces, Academic Press, New York (1975).

Further Notes
