Submission of Papers
Manuscripts should be prepared in English and must be in final form. Authors are requested to submit their original manuscript with two clear hard copies to the above address. We do not accept electric submission. We welcome manuscripts prepared in LaTeX2e (and AMS-LaTeX 2.0). When papers written in TeX are accepted, the authors will be requested to send an electronic copy of their paper with the final version of the manuscript to the Editors. Papers should include

(a) a short but informative abstract,
(b) classification numbers at the foot of the first page according to the 2000 Mathematical Subject Classification (MSC2000), to be found in http://www.ams.org/msc,
(c) the author's address, including e-mail address.

Proofs
Proofs will be sent to the author (the first named author if no other author is specifically indicated in the case of multi-authored papers) and should be returned within 72 hours of receipt.

Reprints
Fifty free reprints of each paper will be provided.
