Priv.-Doz. Andreas Zastrow
Between October 1985 and Sept. 2000 I hold under various
positions offices at Bochum's Mathematical Institute
(chair of Algebra and Topology, Prof. Dr. Dr. h.c. H. Zieschang).
I am now based at the University of Gdansk (Gdansk, Poland),
and meanwhile I also transferred my web-page
There you will find the data, that you used to find here.
