The reason why these notes are written is the appearance of . I have taken the liberty of including that paper in this document, cf. Appendix C. I had the good fortune of visiting Prof. Tetsuo Tamai, Tokyo Univ., 8–Dec.8, 2009. I read  late November. I then had wished that Tetsuo had given it to me upon my arrival.

A few, smaller updates, were added till about 2004.
