It publishes papers on research in areas of current interest to the readers. A paper should clearly indicate the relationship of the work described to the most relevant previous work. Most formulae in a paper should be accompanied by brief explanations in English. Mathematical proofs should be given only when they are particularly illuminating or are not burdensome. When proofs are not given, it is common to cite a technical report or other source where interested readers may find them.

An abstract of 100 to 200 words for regular papers, or no more than 50 words for brief contributions and comments, clearly stating the nature and significance of the paper is required at the head of the manuscript.
