Points of style

(a)

The language of the journal is English and the spelling should conform to that of the Oxford English Dictionary or Webster's New World Dictionary.

(b)

The body of the manuscript should be preceded by an untitled summary (maximum length 200 words) which should be a summary of the entire paper, not of the conclusions alone.

(c)

The summary should be followed by a list of not more than six key words; these will be used to compile an annual key word index.

(d)

The paper should be reasonably divided into sections, and if necessary subsections. Numbering of these is optional, but section numbers are generated by the style files. Equations, theorems, lemmas and propositions should be numbered consecutively within each section. Only equations referred to in the text need be numbered.

(e)

Tables and figures should be numbered consecutively and titled. The title should be placed before the body of the table or under the figure. All table columns should have an explanatory heading. Tables should not repeat data which are available elsewhere in the paper, e.g., in a line diagram.

(f)

References to published literature should be numbered in alphabetical order. They should be quoted in the text by numbers in brackets (e.g., [1]) and grouped together at the end of the paper in numerical order. The entries in the Reference List should be presented in the following forms, depending on the type of reference:

• Journal Article
• Book
