For more than a year now, I have been looking for a copy of the following CICMA Concordia preprint :


Author : Helmut Koch
Title : Extendible functions
Preprint, CICMA Concordia University Department of Mathematics preprint, 1990.


I tried to locate a copy at the Fields Institute and the University of Toronto libraries, without success. I have also written to Concordia, again without success. So I will be very very grateful to anyone who can make a copy (electronic or paper) available to me. My email address is mylastname@gmail.com.



Koch's "Extendible functions"
I finally have a copy of Koch's *Extendible functions*, thanks to Sazzad Ali Biswas of the University of Hyderabad, who had got it in Berlin from Ernst-Wilhelm Zink.


Needless to say, I'm willing to share it with anyone who is interested.
