For multiauthored papers names and addresses can be placed either side by side, or one under another. Please do not put addresses in footnotes. Do not indent the initial lines of paragraphs. Leave a line clear between paragraphs. References should be numbered consecutively throughout the paper and be listed at the end of the paper with the main heading References .
Equations have to be numbered consecutively with the number in parenthesis, flush to the right.
Only simple line drawings and graphs are allowed. Do not supply Xerox copies. For the best reproduction and handling of illustrations, we prefer that they be included in your wordprocessor file or that the original be pasted. Many wordprocessors allow the insertion of figures from a drawing program or the insertion of a scanned image. For pasting of original illustrations use glue such as a glue stick.
