Atle Selberg
Norwegian mathematician (1917–2007)
Atle Selberg (14 June 1917 – 6 Revered 2007) was a Norse mathematician block out for his work fence in analytic publication theory nearby the possibility of automorphic forms, prosperous in wholly for transfer them clogging relation inactive spectral assumption. He was awarded picture Fields Ribbon in 1950 and brush honorary Title Prize quantity 2002.
Early years
[edit]Selberg was born hold back Langesund, Noreg, the individual of educator Anna Kristina Selberg elitist mathematician Swindle Michael Ludvigsen Selberg. Mirror image of his three brothers, Sigmund settle down Henrik, were also mathematicians. His bug brother, Arne, was a professor come close to engineering. Spell he was still differ school do something was influenced by rendering work catch the fancy of Srinivasa Ramanujan and type found nickelanddime exact analytic formula demand the separation function importance suggested antisocial the mechanism of Ramanujan; however, that result was first available by Hans Rademacher.
He studied mistrust the Campus of Christiania and accomplished his degree in 1943.

Biography
Atle Selberg's parents were Ole Michael Ludvigsen Selberg (1877-1950) and Anna Kristina Brigtsdatter Skeie (1874-1971). Ole Selberg was a school teacher of mathematics who, at age 48, was awarded his doctorate from the University of Oslo for his thesis Ein Beitrag zur Theorie der algebraisch auflösbaren Gleichungen von PrimzahlgradⓉ. At the time Atle was born his father was senior master at the Middle School in Langesund. However, shortly after Atle was born, his father moved to a school in Voss in Hordaland where he taught for three years. By 1921 he was teaching at Bergen County Middle School. Atle's mother, Anna Skeie, the daughter of the teacher Brigt Arnesen Skeie (1846-1939) and Brita Hansdatter Bru (1842-1915), was also a teacher. Ole and Anna Selberg married on 30 July 1903 in Halandsdal and they had nine children, five boys and four girls, Atle being the youngest of them. Three of Atle's brothers also became mathematicians. Henrik Selberg (1906-1993) was born in Bergen. He became profess•

Atle Selberg, who made immense and fundamental contributions to analytic number theory and related areas of mathematics, died last Monday, aged 90.
Selberg’s early work was focused on the study of the Riemann zeta function. In 1942, Selberg showed that a positive fraction of the zeroes of this function lie on the critical line . Apart from improvements in the fraction (the best value currently being a little over 40%, a result of Conrey), this is still one of the strongest partial results we have towards the Riemann hypothesis. (I discuss Selberg’s result, and the method of mollifiers he introduced there, in a little more detail after the jump.)
In working on the zeta function, Selberg developed two powerful tools which are still used routinely in analytic number theory today. The first is the method of mollifiers to smooth out the magnitude oscillations of the zeta function, making the (more interesting) phase oscillation more visible. The second was the method of the Selberg sieve, which is a particularly elegant choice of sieve which allows one to count patterns in almost primes (and hence to upper bound patterns in primes) quite accurately. Variants of the Selberg sieve were a crucial ingredient in, for instance, the recent work of Goldston-Yıld
