This ebook by way of Jakob Nielsen (1890-1959) and Werner Fenchel (1905-1988) has had
a lengthy and complex background. In 1938-39, Nielsen gave a chain of lectures on
discontinuous teams of motions within the non-euclidean airplane, and this led him - in the course of
World battle II - to write down the 1st chapters of the ebook (in German). while Fenchel,
who needed to get away from Denmark to Sweden a result of German career,
returned in 1945, Nielsen initiated a collaboration with him on what grew to become identified
as the Fenchel-Nielsen manuscript. at the moment they have been either on the Technical
University in Copenhagen. the 1st draft of the Fenchel-Nielsen manuscript (now
in English) used to be complete in 1948 and it used to be deliberate to be released within the Princeton
Mathematical sequence. although, as a result quick improvement of the topic, they felt
that giant alterations needed to be made sooner than e-book.
When Nielsen moved to Copenhagen college in 1951 (where he stayed until eventually
1955), he was once a lot concerned with the overseas association UNESCO, and the
further writing of the manuscript used to be left to Fenchel. The records of Fenchel now
deposited and catalogued on the division of arithmetic at Copenhagen Univer-
sity include unique manuscripts: a partial manuscript (manuscript zero) in Ger-
man containing Chapters I-II (

I -15), and a whole manuscript (manuscript I) in
English containing Chapters I-V (

1-27). The documents additionally comprise a part of a corre-
spondence (first in German yet later in Danish) among Nielsen and Fenchel, the place
Nielsen makes designated reviews to Fenchel's writings of Chapters III-V. Fenchel,
who succeeded N. E. Nf/Jrlund at Copenhagen college in 1956 (and stayed there
until 1974), was once greatly concerned with an intensive revision of the curriculum in al-
gebra and geometry, and focused his learn within the concept of convexity, heading
the foreign Colloquium on Convexity in Copenhagen 1965. for nearly two decades
he additionally placed a lot attempt into his task as editor of the newly begun magazine Mathematica
Scandinavica. a lot to his dissatisfaction, this task left him little time to complete the
Fenchel-Nielsen venture the best way he desired to.
After his retirement from the collage, Fenchel - assisted through Christian Sieben-
eicher from Bielefeld and Mrs. Obershelp who typed the manuscript - discovered time to
finish the ebook undemanding Geometry in Hyperbolic area, which was once released via
Walter de Gruyter in 1989 almost immediately after his dying. concurrently, and with an identical
collaborators, he supervised a typewritten model of the manuscript (manuscript 2) on
discontinuous teams, removal a number of the vague issues that have been within the unique
manuscript. Fenchel informed me that he meditated removal elements of the introductory
Chapter I within the manuscript, seeing that this might be coated through the publication pointed out above;
but to make the Fenchel-Nielsen publication self-contained he finally selected to not do
so. He did choose to omit
27, entitled Thefundamental crew.

As editor, i began in 1990, with the consent of the felony heirs of Fenchel and
Nielsen, to supply a TEX-version from the newly typewritten model (manuscript 2).
I am thankful to Dita Andersen and Lise Fuldby-Olsen in my division for hav-
ing performed a superb task of typing this manuscript in AMS- TEX. i've got additionally had
much support from my colleague J0rn B0rling Olsson (himself a scholar of Kate Fenchel
at Aarhus college) with the evidence analyzing of the TEX-manuscript (manuscript three)
against manuscript 2 in addition to with a normal dialogue of the variation to the fashion
of TEX. In so much respects we determined to stick to Fenchel's intentions. despite the fact that, turning
the typewritten version of the manuscript into TEX helped us to make sure that the notation,
and the spelling of definite key-words, will be uniform during the ebook. additionally,
we have indicated the start and finish of an explanation within the ordinary sort of TEX.
With this TEX -manuscript I approached Walter de Gruyter in Berlin in 1992, and
to my nice reduction and pride they agreed to post the manuscript of their sequence
Studies in arithmetic. i'm so much thankful for this confident and speedy response. One
particular challenge with the booklet became out to be the replica of the numerous
figures that are an essential component of the presentation. Christian Siebeneicher had at
first agreed to convey those in ultimate digital shape, yet by way of 1997 it turned transparent that he
would now not be capable to locate the time to take action. although, the writer provided an answer
whereby I may still convey special drawings of the figures (Fenchel didn't depart such
for Chapters IV and V), after which they might arrange the construction of the figures in
electronic shape. i'm very thankful to Marcin Adamski, Warsaw, Poland, for his tremendous
collaboration in regards to the real construction of the figures.
My colleague Bent Fuglede, who has personaHy recognized either authors, has kindly
written a quick biography of the 2 of them and their mathematical achievements,
and which additionally areas the Fenchel-Nielsen manuscript in its right point of view. In
this connection i want to thank The Royal Danish Academy of Sciences and
Letters for permitting us to incorporate during this publication reproductions of pictures of the 2
authors that are within the ownership of the Academy.
Since the manuscript makes use of a couple of specified symbols, an inventory of notation with brief
explanations and connection with the particular definition within the e-book has been integrated. additionally,
a finished index has been extra. In either circumstances, all references are to sections,
not pages.
We thought of including a whole record of references, yet made up our minds opposed to it because of
the overwhelming variety of study papers during this quarter. as an alternative, a miles shorter
list of monographs and different finished debts proper to the topic has been
My ultimate and such a lot honest thank you visit Dr. Manfred Karbe from Walter de Gruyter
for his commitment and perseverance in bringing this ebook into lifestyles.
