We're excited to have you with us! The publication of his collected mathematical papers is, therefore, timely and very welcome; the more so as the two volumes under review make the papers more readily accessible to today's researchers. Thus, for example, not many mathematicians will in the past have had access to Nielsen's doctoral dissertation, presented to the Universitat Kiel in Other papers appeared in various Scandinavian periodicals or conference proceedings, many of them in Danish: the majority of them, and also many of Nielsen's papers in German, have for this collection been translated into English.

Among them is his fundamental paper, in the Matematisk Tidsskrift inon free groups, in which the Nielsen- Schreier theorem or rather Nielsen's part of it is proved for the first time: now there is no further excuse for misquoting this paper, as has happened repeatedly in the past. There was however, some work by Nielsen which was not published in his collected works.

This was work which he had undertaken with his student and friend Werner Fenchel, the author of the articles [ 2 ] and [ 3 ]and was based on a course of lectures Nielsen gave on the theory of discontinuous groups of isometries of the hyperbolic plane in - In fact Fenchel contributed the final article [ 1 ] on this topic. This piece of mathematics, now known as Fenchel-Nielsen theory, had a rather strange history.

Fenchel and Nielsen decided to write a monograph on the theory but neither were happy with the first draft of the manuscript which they produced. They were working on a revision when Nielsen died in after an illness lasting about eight months. Matters were certainly not helped by the fact that the original manuscript was stolen from Fenchel's car but he continued to feel that the results were unsatisfactory.

Eventually Fenchel wrote a book Elementary geometry in hyperbolic space which was intended to put give an approach with would make presentation of Fenchel-Nielsen theory much clearer. Fenchel died in with the whole project close to completion. References show. J Nielsen, Jakob Nielsen: collected mathematical papers 2 vols. Boston, Mass. Tidskr 85 - Trondheim 331 - 6.
