Discontinuous Groups of Isometries in the Hyperbolic Plane

This ebook through Jakob Nielsen (1890-1959) and Werner Fenchel (1905-1988) has had
a lengthy and complex heritage. In 1938-39, Nielsen gave a sequence of lectures on
discontinuous teams of motions within the non-euclidean aircraft, and this led him - in the course of
World conflict II - to write down the 1st chapters of the e-book (in German). while Fenchel,
who needed to break out from Denmark to Sweden end result of the German profession,
returned in 1945, Nielsen initiated a collaboration with him on what grew to become recognized
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 comprehensive in 1948 and it used to be deliberate to be released within the Princeton
Mathematical sequence. notwithstanding, a result of fast improvement of the topic, they felt
that huge alterations needed to be made prior to booklet.
When Nielsen moved to Copenhagen collage in 1951 (where he stayed till
1955), he used to be a lot concerned with the foreign association UNESCO, and the
further writing of the manuscript used to be left to Fenchel. The data 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 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 college in 1956 (and stayed there
until 1974), was once greatly concerned with a radical revision of the curriculum in al-
gebra and geometry, and targeted his study within the idea 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 began magazine Mathematica
Scandinavica. a lot to his dissatisfaction, this task left him little time to complete the
Fenchel-Nielsen undertaking the best way 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 - chanced on time to
finish the booklet basic Geometry in Hyperbolic area, which used to be 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, elimination the various imprecise issues that have been within the unique
manuscript. Fenchel advised me that he reflected elimination elements of the introductory
Chapter I within the manuscript, due to the fact that this may be coated through the e-book pointed out above;
but to make the Fenchel-Nielsen e-book self-contained he finally selected to not do
so. He did choose to pass over
27, entitled Thefundamental team.

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 evidence analyzing of the TEX-manuscript (manuscript three)
against manuscript 2 in addition to with a basic dialogue of the difference to the fashion
of TEX. In such a lot respects we made up our minds to stick to Fenchel's intentions. notwithstanding, turning
the typewritten variation 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 booklet. additionally,
we have indicated the start and finish of an evidence within the traditional kind of TEX.
With this TEX -manuscript I approached Walter de Gruyter in Berlin in 1992, and
to my nice aid and pride they agreed to post the manuscript of their sequence
Studies in arithmetic. i'm such a lot thankful for this confident and speedy response. One
particular challenge with the booklet grew to become out to be the copy of the various
figures that are a vital part of the presentation. Christian Siebeneicher had at
first agreed to carry those in ultimate digital shape, yet through 1997 it grew to become transparent that he
would no longer be capable to locate the time to take action. in spite of the fact that, the writer provided an answer
whereby I may still convey particular drawings of the figures (Fenchel didn't depart such
for Chapters IV and V), after which they might arrange the creation of the figures in
electronic shape. i'm very thankful to Marcin Adamski, Warsaw, Poland, for his high-quality
collaboration in regards to the genuine creation of the figures.
My colleague Bent Fuglede, who has personaHy identified 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 viewpoint. In
this connection i need to thank The Royal Danish Academy of Sciences and
Letters for permitting us to incorporate during this booklet reproductions of photos 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 publication has been integrated. additionally,
a complete index has been additional. In either instances, all references are to sections,
not pages.
We thought of including a whole record of references, yet made up our minds opposed to it as a result of
the overwhelming variety of learn papers during this zone. as an alternative, a far shorter
list of monographs and different complete bills proper 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 life.

Statistics on Special Manifolds

This e-book is anxious with statistical research at the distinct manifolds, the Stiefel manifold and the Grassmann manifold, taken care of as statistical pattern areas which includes matrices. the previous is represented by way of the set of m x okay 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.
