ABSTRACTS

AbstractThe purpose of this department is to give sufficient information about the subject matter of each publication to enable users to decide whether to read it. It is our intention to cover all books, articles, and other materials in the field.Books for abstracting and eventual review should be sent to this department. Materials should be sent to Prof. David E. Zitarelli, Department of Mathematics, Temple University, Philadelphia, PA 19122, U.S.A. (e-mail: ZIT@VM.TEMPLE.EDU)Readers are invited to send reprints, autoabstracts, corrections, additions, and notices of publications that have been overlooked. Be sure to include complete bibliographic information, as well as transliteration and translation for non-European languages. We need volunteers willing to cover one or more journals for this department.In order to facilitate reference and indexing, entries are given abstract numbers which appear at the end following the symbol #. A triple numbering system is used: the first number indicates the volume, the second the issue number, and the third the sequential number within that issue. For example, the abstracts for Volume 20, Number 1, are numbered: 20.1.1, 20.1.2, 20.1.3, etc.For reviews and abstracts published in Volumes 1 through 13 there are anauthor indexin Volume 13, Number 4, and asubject indexin Volume 14, Number 1.The initials in parentheses at the end of an entry indicate the abstractor. In this issue there are abstracts by Victor Albis (Bogotá), Joe Albree (Montgomery, AL), Irving Anellis (Ames, IA), Thomas L. Bartlow (Villanova, PA), Ronald Calinger (Washington), John G. Fauvel (Milton Keynes), Ivor Grattan-Guinness (Middlesex), Jan P. Hogendijk (Utrecht), Victor J. Katz (Washington), Albert C. Lewis (Hamilton), Laura Nurzia (Rome), Karen V. H.
