Instructions for authors

 
Preferences will be given to papers, not longer than 15 to 20 pages, written preferably in English and typeset by means of a T_EX system. A simple specimen file, exposing in detail the instruction for preparing the manuscripts can be downloaded here. It is also available upon request from the electronic address of the Editorial Board. Two copies of the manuscript should be submitted. Upon acceptance of the paper the authors will be asked to send by electronic mail or on a diskette the text of the papers and the appropriate graphic files (in any format like EPS, TIF PCX, etc.).

The manuscripts should be prepared for publication in accordance with the instructions, given below.

The manuscripts must be typed on one side of the paper in double spacing with wide margins. On the first page the author should provide: a title, name(s) of the author(s), a short abstract, a list of keywords and the appropriate 1995 Mathematical Subject Classification codes (primary and secondary, if necessary). The affiliation(s), including the electronic address, is given at the end of the manuscripts.

Figures are to be inserted in the text nearest their first reference. If the author cannot supply and/or incorporate the graphic files, drawings (in black ink in a good quality paper), should be enclosed separately. If photographs are to be used, only black and white ones are acceptable.

Tables should be inserted in the text as close to the point of reference as possible. Some space should be left above and below the table.

Footnotes, which should be kept to a minimum and should be brief, must be numbered consecutively.

References must be cited in the text in square brackets, like [3], or [5, 7], or [11, p. 123], or [16, ch. 2.12]. They are to be numbered either in the order they appear in the text or alphabetically. Examples are please note order, style and punctuation):
