Discontinuous Groups of Isometries in the Hyperbolic Plane
This booklet via Jakob Nielsen (1890-1959) and Werner Fenchel (1905-1988) has had
a lengthy and complex background. In 1938-39, Nielsen gave a sequence of lectures on
discontinuous teams of motions within the non-euclidean airplane, and this led him - in the course of
World conflict II - to put in writing the 1st chapters of the ebook (in German). while Fenchel,
who needed to get away from Denmark to Sweden as a result of the German career,
returned in 1945, Nielsen initiated a collaboration with him on what turned 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) was once accomplished in 1948 and it was once deliberate to be released within the Princeton
Mathematical sequence. notwithstanding, as a result of the quick improvement of the topic, they felt
that gigantic adjustments needed to be made earlier than e-book.
When Nielsen moved to Copenhagen collage in 1951 (where he stayed till
1955), he was once a lot concerned with the foreign association UNESCO, and the
further writing of the manuscript was once left to Fenchel. The data of Fenchel now
deposited and catalogued on the division of arithmetic at Copenhagen Univer-
sity comprise unique manuscripts: a partial manuscript (manuscript zero) in Ger-
man containing Chapters I-II (
I -15), and an entire manuscript (manuscript I) in
English containing Chapters I-V (
1-27). The information additionally comprise a part of a corre-
spondence (first in German yet later in Danish) among Nielsen and Fenchel, the place
Nielsen makes distinct reviews to Fenchel's writings of Chapters III-V. Fenchel,
who succeeded N. E. Nf/Jrlund at Copenhagen collage in 1956 (and stayed there
until 1974), was once greatly concerned with an intensive revision of the curriculum in al-
gebra and geometry, and centred his examine within the idea of convexity, heading
the overseas Colloquium on Convexity in Copenhagen 1965. for nearly twenty years
he additionally placed a lot attempt into his task as editor of the newly all started magazine Mathematica
Scandinavica. a lot to his dissatisfaction, this task left him little time to complete the
Fenchel-Nielsen venture the way in which he desired to.
After his retirement from the college, Fenchel - assisted by means of Christian Sieben-
eicher from Bielefeld and Mrs. Obershelp who typed the manuscript - came upon time to
finish the booklet easy Geometry in Hyperbolic house, which used to be released by means of
Walter de Gruyter in 1989 presently after his loss of life. at the same time, and with an analogous
collaborators, he supervised a typewritten model of the manuscript (manuscript 2) on
discontinuous teams, removal some of the imprecise issues that have been within the unique
manuscript. Fenchel advised me that he pondered elimination elements of the introductory
Chapter I within the manuscript, due to the fact this is able to be lined via the booklet pointed out above;
but to make the Fenchel-Nielsen e-book self-contained he finally selected to not do
so. He did choose to miss
27, entitled Thefundamental staff.
As editor, i began in 1990, with the consent of the criminal 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 activity of typing this manuscript in AMS- TEX. i've got additionally had
much aid from my colleague J0rn B0rling Olsson (himself a pupil of Kate Fenchel
at Aarhus collage) with the facts studying of the TEX-manuscript (manuscript three)
against manuscript 2 in addition to with a basic dialogue of the variation to the fashion
of TEX. In so much respects we determined to keep on with Fenchel's intentions. even if, turning
the typewritten version of the manuscript into TEX helped us to make sure that the notation,
and the spelling of sure key-words, will be uniform in the course of the publication. additionally,
we have indicated the start and finish of an explanation within the ordinary kind of TEX.
With this TEX -manuscript I approached Walter de Gruyter in Berlin in 1992, and
to my nice aid and delight they agreed to post the manuscript of their sequence
Studies in arithmetic. i'm so much thankful for this optimistic and quickly response. One
particular challenge with the booklet grew to become out to be the replica of the numerous
figures that are a vital part of the presentation. Christian Siebeneicher had at
first agreed to bring those in ultimate digital shape, yet via 1997 it grew to become transparent that he
would now not be capable of locate the time to take action. despite the fact that, the writer provided an answer
whereby I should still carry targeted drawings of the figures (Fenchel didn't depart such
for Chapters IV and V), after which they might manage the construction of the figures in
electronic shape. i'm very thankful to Marcin Adamski, Warsaw, Poland, for his positive
collaboration about the real creation of the figures.
My colleague Bent Fuglede, who has personaHy recognized either authors, has kindly
written a brief biography of the 2 of them and their mathematical achievements,
and which additionally locations the Fenchel-Nielsen manuscript in its right standpoint. In
this connection i want to thank The Royal Danish Academy of Sciences and
Letters for permitting us to incorporate during this ebook reproductions of photos of the 2
authors that are within the ownership of the Academy.
Since the manuscript makes use of a couple of designated symbols, a listing of notation with brief
explanations and connection with the particular definition within the e-book has been integrated. additionally,
a accomplished index has been additional. In either situations, all references are to sections,
not pages.
We thought of including an entire record of references, yet determined opposed to it as a result of
the overwhelming variety of learn papers during this zone. in its place, a far shorter
list of monographs and different entire money owed appropriate to the topic has been
collected.
My ultimate and so much honest thank you visit Dr. Manfred Karbe from Walter de Gruyter
for his commitment and perseverance in bringing this ebook into lifestyles.
Statistics on Special Manifolds
This publication is worried with statistical research at the designated manifolds, the Stiefel manifold and the Grassmann manifold, taken care of as statistical pattern areas along with matrices. the previous is represented through the set of m x ok matrices whose columns are collectively orthogonal k-variate vectors of unit size, and the latter by means of the set of m x m orthogonal projection matrices idempotent of rank ok.
