Biography
Born April 18, 1907 in Helsingfors (now Helsinki) [4] . From 1924 to 1928 he studied at the University of Helsinki , where from 1933 to 1936 he held the position of associate professor.
In 1936, along with Jesse Douglas, Alfors became one of the first two mathematicians awarded the Fields Prize [4] . The award was presented to him for his contribution to the development of the theory of Riemann surfaces and the development of the theory of quasiconformal mappings.
In 1944, he received an offer to work in the Swiss Higher Technical School of Zurich , which he accepted after the end of the war in 1945, but the next year he moved to work in the USA at Harvard University , where he stayed until his retirement in 1977 [4] .
In 1981, he was awarded the Wolf Prize in Mathematics [4] "for productive discoveries and the creation of powerful new methods in the geometric theory of functions." In 1988, he became a foreign member of the USSR Academy of Sciences [3] .
Alfors's works are mainly devoted to the theory of complex analysis, the theory of Riemann surfaces, the theory of conformal and quasiconformal mappings, and the theory of geometric functions. He is the author of several literary works, one of his most famous works is the book “Complex Analysis” published in 1953 [4] .
