Arthur Erdélyi

FRSE (2 October 1908 – 12 December 1977) was a Hungarian-born British mathematician. Erdélyi was a leading expert on special functions, particularly orthogonal polynomials and hypergeometric functions.[2][3]

Biography

He was born Arthur Diamant in

Jew, and so it was difficult for him to receive a university education in his native Hungary. He travelled to Brno, Czechoslovakia, to obtain a degree in electrical engineering
. However, after his flair for mathematics was discovered (he won several prizes in a competition in his first year), he was persuaded to study the subject.

He soon after began to conduct theoretical research into mathematics, and his first paper was published in 1930. At the end of 1936, he had already published 18 papers, and 11 more appeared in 1937. However, due to the German occupation of Czechoslovakia and neighbouring countries, Erdélyi was forced to flee the country.

Erdélyi contacted

Edmund Whittaker, a fellow expert in hypergeometric functions, asking for his assistance and soon after, Erdélyi travelled to Edinburgh, Scotland, after receiving £400 for a visa from Whittaker. He joined the University of Edinburgh, and after 2 years there, became a lecturer in the Department of Mathematics (after gaining a DSc in 1940 based on his already extensive published work).[4]

In 1946, after

Caltech, California
as a Visiting Professor. He returned to Edinburgh in 1948, only to resign in 1949 to assume the position of Professor of Mathematics at the California Institute of Technology. This was a post he was to hold for the next 15 years, and he retained his citizenship of Britain while in the United States.

In 1964, he returned to Edinburgh as a Professor of Mathematics, a position he held until his death in 1977.

He died in Edinburgh.[5]

Family

He married Eva Neuburg in 1942. They did not have children.

Research

Erdélyi was primarily an expert in special functions, in particular,

fractional integration. He wrote two books of high standing - Asymptotic Expansions (1955) (reprinted by Dover
) and Operational Calculus and Generalised Functions (1962)

Works

Awards

Erdélyi received several honours, including being elected to the Royal Society as a Fellow in 1975.[1] He also became a fellow of the Royal Society of Edinburgh in 1945, and was also elected a member of the Academy of Sciences of Turin.
