4、 3–5 keywords; 。

5、 2000 MR (Mathematical Reviews) Subject Classification; and 。

6、 an abbreviated title not exceeding 45 characters (including spaces) for the running head.1.3Manuscript should be typed in double-spaced and single-sided on A4 sheets. Once a paper is accepted, the author(s) will be requested to send the final manuscript in hardcopy (or PDF or PS file) as well as an electronic file (Latex, Amstex, or CCT) in the format required by CAM via e-mail to edcam@fudan.edu.cn or on diskettes to the Editorial O ce.1.4References should be cited in the text using Arabic numerals within square brackets, and listed at the end of the paper in numerical order.For journals:[reference number] surname(s), initial(s), paper title, abbreviated title of the journal, volume number(issue number), year of publication, relevant page numbers.For books:[reference number] surname(s), initial(s), Book Title, publishing house, site of publication, year of publication.For proceedings:[reference number] surname(s), initial(s), paper title, Title of the Proceedings, editor(s) (ed(s).), publishing house, site of publication, year of publication, relevant pages.2 All papers will be refereed.
