Back to the beginning
The cover photo is showing me playing a piece of Johann Sebastian Bach at the "Riemenhaus" in
Here is an older one showing me (in 1963, when I was a student in Göttingen) hiking on the peninsula of Athos.
This and the next photo were shot after the day of a typhoon at a famous shrine (Dazaifu) south of Fukuoka in the 1990's during one of my several visits to Japan with my wife Kyoko.
In 2016 we have been in October on Mt. Rokko, in Kagoshima and again in Fukuoka.
Here are some photos from our last stay from October to November 2017. Near Fukuoka, we visited the hometown of the famous Japanese Composer Rentaro Taki, and I performed his piece Kojo no tsuki (moon over the ruined castle) at his statue on the ruins of Oka castle. During a conference in Kagoshima we could marvel again at the smoking Mt. Sakurajima and the beginning of autumnal tints at Lake Rokukannonmiike.
The next photo was taken (in a similar style of almost all participants) at the occasion of the 75th birthday of Professor Kneser in Göttingen in the Auditorium Maximum of the Mathematisches Institut. It imitades a well known photo of David Hilbert showing him exactly at the same place when delivering a lecture with one of his printed papers in his hand.
On October 29, 2016, there has been a small ceremony in the same lecture hall in memory of the "Goldenes Doktorjubiläum" of a few persons.
Here is a small selection of my favorite personal links for
1. buying books via
Springer and AMS
2. searching new mathematical literature via LANL
3. getting information about music and, in particular, opera
4. Musik-Vermittlung (homepage of my daughter Stephanie Riemenschneider)
If you are interested, you
may find here a biography of Tilman Riemenschneider (more detailed information
is given in the German edition), his selfportrait and one of
his works . Please also contact the Mainfränkisches Museum in Würzburg. - My own "creations" in pictorial arts were always rather abstract culminating in sketches like
the divisor with normal crossings à la Mirò.
in particular: complex-analytic
and complex-algebraic geometry and especially
In the next few months I shall attach here some partially incomplete chapters of a quite old singularity project.
Please read more in the
and then go according to the actualized List of Contents there to the Chapter you are interested in:
Chapter 1 , Chapter 2 , Chapter 3 , Chapter 4 , Chapter 5 etc.
In order to get a satisfactory print out
of 2 pages on one sheet of paper one should use the
option in Adobe of adding an extra
page at the beginning.

6. an elementary introduction to group theory and mathematical puzzles for highschool students
