Svante Janson 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-statistic
s. In combinatorics
, Janson has publications in probabilistic combinatorics, particularly random graph
s and in the analysis of algorithms
: In the study of random graphs, Janson introduced U-statistics and the Hoeffding
decomposition.
Janson has published four books and over 200 academic papers .
in mathematics, Janson took high-school and even university classes while in primary school. He was admitted in 1968 to Gothenburg University
at age 12. After his 1968 matriculation at Uppsala University at age 13, Janson obtained the following degrees in mathematics: a "candidate of philosophy" (roughly an "honours" B.S. with a thesis) at age 14 (in 1970) and a doctor of philosophy
at age 21–22 (in 1977). Janson's Ph.D. was awarded on his 22nd birthday. 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 1987 Janson became the chaired professor of mathematics at Uppsala university. Traditionally in Sweden, the chaired professor has had the role of a "professor ordinarius" in a German university (roughly combining the roles of research professor and director of graduate studies at a research university in the USA).
Svante Janson's full name is "Carl Svante Janson".
(KVA), Svante Janson is a member of Uppsala's Royal Scientific Society. His thesis received the 1978 Sparre Award from the KVA. He received the 1994 Swedish medal for the best young mathematical scientist, the Göran Gustafsson prize. Janson's former doctoral student
, Ola Hössjer, received the Göran Gustafsson prize in 2009, becoming the first statistician
so honored.
In December 2009, Janson received the Eva & Lars Gårding
prize from the Royal Physiological ("Fysiografiska" in Swedish
) Society in Lund, Sweden.

A child prodigy is someone who, at an early age, masters one or more skills far beyond his or her level of maturity. One criterion for classifying prodigies is: a prodigy is a child, typically younger than 18 years old, who is performing at the level of a highly trained adult in a very demanding...
