Back to the beginning
Complex analysis
(in several variables),
in particular: complex-analytic
and complex-algebraic geometry and especially
singularities .
In the next few months I shall attach here some partially incomplete chapters
of a quite old singularity project.

In a Prospective
Preface you find a tentative list of contents
for the complete text in preparation.
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.

For German reading persons,
there are two other texts:
6. a German
version of 4. (see also text of the 2016
paper)
7. an elementary introduction to group theory and
mathematical puzzles

Following there are some photos and a picture related to
Emil Artin (03.03.1898 - 20.12.1962)
and
Erich Kähler (16.01.1906 - 31.05.2000),
my predecessors on my position in Hamburg.
(My successor in Hamburg was Bernd Siebert; in 2018 he moved to the University of Texas at Austin.
My successors on my position in Göttingen were Michael Schneider and Hubert Flenner).
1. Artin and Kähler in a garden café.
2. Artin playing the flute (water-colour painting by Heinrich Stegemann. Stegemann also produced a
life-mask that is exhibited in the "Artin-Hörsaal" in the main building of the Universität Hamburg.
See also Nr. 47 on page 177 in Kunstschätze und Wissensdinge. Eine Geschichte der Universität Hamburg
in 100 Objekten. Herausgegeben von Iris Wendenholm und Christina Posselt-Kuhli. Michael Imhof Verlag,
Petersberg, 2019).
3. Death-mask of Artin (property of and photo by OR). A more professional photo (copyright
Karin Plessing and Reinhard Scheiblich) appeared together with some further historical facts in the volume
dedicated to the 100th anniversary of the Universität Hamburg, see loc.cit., Nr. 48 on p. 179).
To my knowledge, it has been the first time mentioned and reproduced in Band 28, Heft 1/2, Februar 1965
of the Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, EMIL ARTIN IN MEMORIAM,
saying in the subtitle: Photogr. Wiedergabe der von Schneller, Hamburg, geschaffenen Totenmaske.
In Der Neue Rump, Lexikon der bildenden Künstler Hamburgs, Wachholtz Verlag, Neumünster/Hamburg, 2013,
one finds the claim that Robert Schneller (Emil John Carl Robert Schneller, 25.03.1901 - 28.01.1980)
manufactured the death-mask in 1962. This is, however, not possible. It has been finished in 1963, according to the following
4. Signature on the plaster cast of the death-mask. It obviously shows the year 1963 and the signature
"R. Schneller" (compare with a sketch signed by Robert Schneller around the time of Artins death -
courtesy of Dr. Nele Lipp in Hamburg).
It is my pleasure to thank my friend and piano accompanist Dr. Christoph Thiemann for helpful discussions and investigations, especially for finding out
the date of death of Robert Schneller by searching through the volumes of the Geburts-General-Register of the Freie und Hansestadt Hamburg.
5. My desk.
A good survey on Mathematics in Hamburg you can find in the article Die ersten 100 Jahre Mathematik an der Universität Hamburg
by Benedikt Löwe and Deniz Sarikaya, pp. 29 - 58, in: 100 Jahre Universität Hamburg, Band 4, Mathematik - Informatik - Naturwissenschaften - Medizin.
Ed.: Rainer Nicolaysen, Eckart Krause und Gunnar B. Zimmermann, Wallstein Verlag, Göttingen 2024.
However, the sentence on p. 55:
Oswald Riemenschneider berichtet, er habe in der Zeit seiner Schriftleitung (1978 bis 1984) vergeblich versucht, ihren Namen zu ändern, um dem Eindruck entgegenzuwirken, die Zeitschrift decke ausschließlich die reine Mathematik ab
is incorrect!
Back to the beginning
1. buying books via
Springer and AMS
2. searching new
mathematical literature via arXiv
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
(Sammlung/Sammlungsbereiche/Riemenschneider) in Würzburg. -
My own "creations" in pictorial arts were always rather abstract
culminating
in sketches like the divisor with normal crossings à la Mirò.
On the cover photo I am 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.
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.
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, at some waterfalls near Kagoshima
and hiking again in the hills near Fukuoka.
Here are some photos from our last stay from October to
November 2017.
Near Fukuoka, we visited this time 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.
I attach here
from time to time just a few of my own favourite
personal photos.
