2006 mathematics prize announced

Swedish mathematician Lennart Carleson has been named as the winner of the 2006 Abel Prize for outstanding work in the field of mathematics.
The prize is worth about £520,000, and credits a discipline overlooked by the Nobel Prizes.
The honour recognises Professor Carleson's work in harmonic analysis, particularly for his proof of the Fourier series.
The prize is awarded by the Norwegian Academy of Science and Letters.
Professor Carleson told the BBC News website that he felt grateful and humble on receiving the news, announced on Thursday in Oslo.
"There are so many good people that could have been chosen, so I feel very lucky," he said.
He will be presented with his prize by the King of Norway at an award ceremony on 23 May.
The international Abel Committee, which decided on the winner, said: "Carleson is always far ahead of the crowd. He concentrates on only the most difficult and deep problems.
"Once these are solved, he lets others invade the kingdom he has discovered, and he moves on to even wilder and more remote domains of science."
