It ranges over the whole spectrum of mathematics and also reflects the changing momentum ofdialogue between hitherto distinct areas of pure and applied parts of the discipline. The editorial board has been chosen accordingly and will from time to time be recomposed to represent the full diversity of mathematics as covered by Mathematical Reviews. This is a rapid means of publication for current material whose style of exposition is that of a developing subject. Work that is in most…
