INSTRUCTIONS TO AUTHORS

Authors are cordially invited to submit papers on subjects of pure and applied mathematics to the Editor-in-Chief, at the address below, or directly to a member of Editorial Board.

Manuscripts should be typeset in English with double spacing on good quality A4-format white papers by using AMS-TEX or AMS-LATEX. All manuscripts should be submitted by e-mail to jongkyuk@kyungnam.ac.kr or kksmj@kyungnam.ac.krAnd also you can submit your manuscript by online : Online Submissions. The authors will be asked to submit their accepted manuscripts electronically. No changes should be made in the mathematics of the manuscript at this stage.

The title of the manuscript should be typed in capital letters bold face. The name of the authors should be centered at the top of page 1. After the authors' names, the addresses (with e-mail addresses) of the authors should appear at the end of the paper. And also, it is desirable to include an Abstract which should not exceed 200 words. The authors should also include, as footnotes for page 1, Keywords and Phrases as well as 2010 Mathematics Subject Classifications. Other footnotes may also be included in the first page about supporting grants, presentations, etc. Footnotes on pages other than the first should be avoided. The width (resp. deep) of the text of the final submitted version of the paper should be exactly 13cm (resp. 19cm). Titles of all principal Sections, Acknowledgement, and Appendices should be typed centered capitalized bold face in the same font as the manuscript. For more details, you can see the informations at the menu online submissions.

References should be listed in alphabetical order according to the surnames of the first author at the end of the paper and should be cited in the text as, e.g., [2] or [3, Theorem 4], etc. It is suggested that the authors make concrete references to the items of the References section.
