Who formulated the hypothesis of the so-called `Biberbaha`

Born Ludwig Bieberbach in Goddelau (Goddelau), which is near Darmstadt (Darmstadt); He first studied in Heidelberg (Heidelberg), and then - in Gottingen (G & # 246; ttingen), under the leadership of Felix Klein (Felix Klein). In 1910 Bieberbach finished his doctoral thesis on the problems of the theory of automorphic functions, and received a well-deserved degree. In 1910, Ludwig became assistant professor in Konigsberg (K & # 246; nigsberg); three years later he got a professorial chair at the University of Basel (University of Basel). In 1915 Ludwig taught at the University of Frankfurt (University of Frankfurt), and rabotatv Berlin University (University of Berlin) settled in 1921-m, where stayed until 1945.

In 1911 Bieberbach wrote a paper on the Euclidean motions; later it was this article has helped to solve the 18-th Hilbert problem (Hilbert`s 18th problem). Ludwig actively worked on complex analysis and its practical application in various areas of mathematics. In 1916 he formulated the so-called `hypothesis Biberbaha` (Bieberbach conjecture). Finally, this hypothesis has been proven only in 1984, Louis de Branges (Louis de Branges); and in fact it is now known as the `theorem de Branzhe` (de Branges` theorem). Ludwig himself was able to perpetuate his name in spatial groups theorem.

Bieberbach was never an active figure in the Nazi party, but on the whole fascist acts explicitly supported. It is known that Ludwig was involved in the persecution of Jewish scholars - like Landau Edmund (Edmund Landau) and Isai Schur (Issai Shur). Hard enough to Bieberbach influenced other German mathematician - and an anti-Semite - Theodore Whalen (Theodore Vahlen); Together they founded the movement `German matematika` (` Deutsche Mathematik`) and released the eponymous magazine. The aim of the movement was the development of the German, intuitionist school of mathematics. It should be noted that Bieberbach and Valen project was only a small part is actively developing then Nazi Germany on giving science racial characteristics of the project - at the same time actively operated `fiziki` German, German` `himiki` and German biologi`.

In 1945 Bieberbach paid dearly for their cooperation with the Nazis - it drove from all their positions. Only in 1949, Ludwig Ostrowski invited to give a course of lectures at the University of Basel; Alexander Markovich was confident that the political views of the scientist nor in any way affect his professional skills.

Ludwig Bieberbach died on September 1, 1982 and; at the time of his death he was 95 years old.
