This monograph is dedicated to 2 wonderful mathematicians, Karel Löwner (1893–1968) and Lipman Bers (1914–1993), whose lives are dramatically interlinked with key historic occasions of the twentieth century. ok. Löwner, Professor of arithmetic on the German collage in Prague (Czechoslovakia), used to be disregarded from his place simply because he was once a Jew, and emigrated to the us in 1939 (where he replaced his identify to Charles Loewner). past, he had released a number of impressive papers in advanced research and a masterpiece on matrix features. particularly, his ground-breaking parametric approach in geometric functionality conception from 1923, which ended in Löwner’s celebrated differential equation, introduced him world-wide status and grew to become out to be a cornerstone in de Branges’ facts of the Bieberbach conjecture. all at once, Löwner’s differential equation has received contemporary prominence with the creation of a conformally invariant stochastic technique known as stochastic Loewner evolution (SLE) through O. Schramm in 2000. SLE beneficial properties in Fields Medal citations from 2006 and 2010. L. Bers used to be the ultimate Prague Ph.D. pupil of okay. Löwner. His dissertation on strength idea (1938), accomplished presently earlier than his emigration and lengthy considered irretrievably misplaced, was once present in 2006. it's the following made available for the 1st time, with an intensive statement, to the mathematical community.

This monograph provides an in-depth account of the lives of either mathematicians, with targeted emphasis at the pre-war interval. Löwner’s instructing actions achievements are awarded within the context of the existing complicated political scenario and opposed to the history of the broader improvement of arithmetic in Europe. every one of his courses is observed through an in depth observation, tracing the foundation and motivation of the matter studied, and describing the state-of-art on the time of the corresponding mathematical box. detailed awareness is paid to the impression of the consequences acquired and to the later improvement of the underlying principles, hence connecting Löwner’s achievements to present examine job. The textual content is predicated on an intensive archival seek, and many of the archival findings seem the following for the 1st time.

Anyone with an curiosity in arithmetic and the heritage of arithmetic will take pleasure in examining this publication approximately well-known mathematicians of the twentieth century.

Veblen: In our sessions Mr. L¨owner (Prague) was mentioned several times and the expressions concerning him reflected a very high opinion. Would you have some idea, what could be done to help him? It might not be possible 52 2 Karl L¨owner: distinguished teacher and scholar On 15th March 1939, the Nazis occupied Bohemia and Moravia and the Protectorate of Bohemia and Moravia was proclaimed. 87 The L¨owners decided to emigrate to Great Britain. 89 to find a teaching position so quickly. But perhaps the Institute could send him a formal invitation, in case a certain amount of money is available, as seems to be the case based on the enclosed letter.

Ein Vorstoß der K¨olner Fakult¨at beim Minister, L¨owner durch Ernennung zum pers¨onlichen Ordinarius in K¨oln zu halten, hatte keinen Erfolg. 51 However, despite good relations with both his colleagues and students of Cologne, L¨owner was probably not satisfied there;52 the local mathematical community proved to be less than inspiring for his mathematical research.

The Nazis occupied the so-called Sudetenland. During the winter of 1938, because of growing Nazi influence at the German University in Prague, it was becoming apparent that L¨owner’s situation would soon be difficult. From the end of 1938, he was no longer permitted to lecture,77 and he clearly 77 At the end of 1938 about 20% of the students and 30% of the educators at the German University in Prague were of Jewish origin, many of whom had found refuge in Prague by emigrating from Nazi Germany.
