Prof B.Schefold FB2 Goethe Universitat Postfaah 11 19 32 D-6000 Frankfurt 11 BRD Feb.25,1986 Dear Bertram, Thank you for your letter. From my point of view your suggestions imply an unusual amount of bother. Why can not Heinz Kurz or you tell me in writing what your questions are? Unfortunately your letter does notrgive me the slightest indication of what it is really about. If it is a matter of algebraic plunders, unclear formulation, inconsistency etc and other formal points it should be possible to communicate this in a few lines without need for diplomatic missions. I shall be quite grateful for any reminders to put more order into my algebra than I usually have. Beyond that you no doubt realise that no amount of editorial efforts will enable you to hide from the readers the substantial difference of opinion which exists between contributors. Nor is this in itself necessarily a disadvantage. Indeed it might be considered a virtue of the volume if it were able to bring out the differences of existing opinions. With best wisbhe Yours, Josef Steindl
