Hjalmar Mellin
Robert Hjalmar Mellin (born June 19, 1854 in Tyrnävä ( Liminka parish ), † April 5, 1933 in Helsinki ) was a Finnish mathematician who was best known for the Mellin transformation he developed .
Life
Mellin was the son of a clergyman. He grew up in Hämeenlinna , where he also attended school, and then studied at the University of Helsinki . His teacher there was the mathematician Gösta Mittag-Leffler . In 1881 Mellin submitted his dissertation. In 1881/82 he studied in Berlin under Karl Weierstrass . From 1884 to 1891 he was a lecturer in Stockholm, where he did not give any lectures. He then worked as a lecturer in mathematics at the Polytechnic Institute. From 1904 to 1907 he was director of the polytechnic institute and in 1908 became a professor. He retired in 1926. He was a co-founder of the Finnish Academy of Sciences.
His mathematical research led to the development of the important Mellin transform. Related to this , he studied gamma functions , hypergeometric functions , Dirichlet series and the Riemann sche function . Unusually for a mathematician, in the last years of his life he wrote some critical philosophical works on the theory of relativity , whose spacetime concept he rejected. See also: Critique of the theory of relativity .
