The recent abstract of joint work by Atish Bagchi and me contained an erroneous email address for Atish: It should be axb32@po.cwru.edu. However, Atish will not be getting his email for a couple of weeks since he is out of the country. We hope he will return by early November. -- Charles Wells Department of Mathematics, Case Western Reserve University University Circle, Cleveland, OH 44106-7058, USA 216 368 2893 ==============================================================================
