Svante Janson

Carl Svante Janson (born 21 May 1955) is a Swedish mathematician. A member of the Royal Swedish Academy of Sciences since 1994, Janson has been the chaired professor of mathematics at Uppsala University since 1987.

In mathematical analysis, Janson has publications in functional analysis (especially harmonic analysis) and probability theory. In mathematical statistics, Janson has made contributions to the theory of U-statistics. In combinatorics, Janson has publications in probabilistic combinatorics, particularly random graphs and in the analysis of algorithms: In the study of random graphs, Janson introduced U-statistics and the Hoeffding decomposition.

Biography Svante Janson has already had a long career in mathematics, because he started research at a very young age. Lennart Carleson was the doctoral supervisor of Svante Janson, who received his Ph.D. on his 22nd birthday.

From prodigy to docent A child prodigy in mathematics, Janson took high-school and even university classes while in primary school. He was admitted in 1968 to University of Gothenburg at age 12. After his 1968 matriculation at Uppsala University at age 13, Janson's doctoral dissertation was supervised by Lennart Carleson, who had himself received his doctoral degree when he was 22 years old.

After having earned his doctorate, Janson was a postdoc with the Mittag-Leffler Institute from 1978 to 1980. Thereafter he worked at Uppsala University. Janson's ongoing research earned him another PhD from Uppsala University in 1984 – this second doctoral degree being in mathematical statistics; the supervisor was Carl-Gustav Esseen.

In 1984, Janson was hired by Stockholm University as docent (roughly associate professor in the USA).

In December 2009, Janson received the Eva & Lars Gårding prize from the Royal Physiographic Society in Lund.
