LAMBEK FESTSCHRIFT - CALL FOR PAPERS The (electronic) journal "Theory and Applications of Categories" has agreed to publish a special volume in honour of the work of our colleague Joachim Lambek, in celebration of his 75th birthday, which was marked by a symposium at McGill on his actual birthday last December 5th, 1997. We welcome submissions to this volume from anyone interested. All papers submitted will undergo the usual TAC referee process, and we are hopeful that the final volume will be ready before summer 1999. (For the TAC home page, see <http://www.tac.mta.ca/tac/>). Topics suitable for the volume include any of the subjects to which Jim Lambek has contributed which fall roughly within the scope of TAC. For example, categorical algebra, categorical logic and proof theory, mathematical linguistics, algebra and ring theory (preferably with some categorical application or methodology), categorical computer science, etc. We would like to note that a companion volume is also being prepared by the journal "Mathematical Structures in Computer Science" - there may still be room for a very small number of short-to-moderate-length papers to be included in that volume. If you wish your submission to be considered for that, please indicate this when you submit your paper to us. (Of course, MSCS's emphasis is more towards computer science). The submission deadline for the Lambek Fest volume is 30 January, 1999. Please send a postscript file (uuencoded and compressed, if possible) to rags@math.mcgill.ca, or 3 paper copies to R.A.G. Seely Department of Mathematics McGill University 805 Sherbrooke St W Montreal, Quebec Canada, H3A 2K6 (If possible) please send an email message to rags@math.mcgill.ca indicating the title (and authors, if other than the sender of the email) of the paper, as well as an abstract (in standard ascii format, maximum 1 page) of the paper. A technical point: TAC can only accept files prepared with some "flavour" of TeX or LaTeX - most authors ought to be able to arrange for such a file to be prepared from their paper, but if you have problems, let us know and we shall see if we can provide helpful advice. General advice for preparation of papers, including suitable macros, may be found at the TAC home page, <http://www.tac.mta.ca/tac/>.
