While great care will be taken of manuscripts and files, no responsibility can be accepted for any loss. In their own interest, authors are advised to keep a copy of everything they send.

. Preparation of Manuscripts: Manuscripts will be typeset using the LATEX typesetting system. Authors are invited to submit a LATEX file of their paper by e-mail, or if this is not possible to send three copies of their article by post. In the latter case the article should be printed on one side only of white A4 size paper. Files should be prepared using the LATEX article style or the AMS-TEX preprint style. Authors are requested to use only Standard LATEX or AMS-TEX commands and environments. Figures and other artwork should be submitted in electronic form wherever possible. Windows metafile (wmf) or Postscript (ps,eps) are the preferred formats, but a separate Word file of each figure may be suitable. More detailed information, and a style-file for preparing the final form of accepted articles, will soon be available from this site.

Authors who are unable to produce a suitable LATEX or AMS-TEX file may submit three wordprocessor or typewritten copies of their article by post, printed with wide margins on one side only of A4 size white paper. If accepted for publication the article will be typeset in LATEX by the Journal. Authors should be aware, however, that submitting a suitable LATEX file will substantially shorten the time taken to process their paper.

. Deadline for Submissions: Manuscripts may be submitted at any time.

. Offprints: Twenty Four offprints of each article will be supplied free of charge. Additional offprints may be ordered prior to publication and will be charged at cost.

. Copyright: No manuscript should be submitted which has previously been published, or which has been simultaneously submitted for publication elsewhere. The copyright in a published article rests solely with the Faculty of Science of Hacettepe University, and the paper may not be reproduced in whole in part by any means whatsoever without prior written permission.

. Notice: The contents of a paper published in this Journal are the sole responsibility of the author or authors, and its publication does not imply the concurrence of the Editors or the Publisher.
