Grigory
Perelman, a
reclusive Russian mathematics genius who made headlines earlier this year for
not immediately embracing a lucrative math prize, has decided to decline the
cash.

Perelman's decision was announced Thursday by the Clay
Mathematics Institute in
Cambridge, Mass., which had awarded Perelman its Millennium Prize.

The award honors his solving of the Poincare (pwan-kah-RAY)
conjecture, which deals with shapes that exist in four or more dimensions.

Jim Carlson, institute president, said Perelman's decision
was not a complete surprise, since he had declined some previous math prizes.
