## PoincarÃ© Conjecture

Posted on August 15, 2006 Comments (4)

The PoincarÃ© Conjecture in simple terms “states that the three-sphere is the only type of bounded three-dimensional space possible that contains no holes. This conjecture was first proposed in 1904 by H. PoincarÃ©” – Mathworld

Elusive Proof, Elusive Prover: A New Mathematical Mystery:

Also left hanging, for now, is $1 million offered by the Clay Mathematics Institute in Cambridge, Mass., for the first published proof of the conjecture, one of seven outstanding questions for which they offered a ransom back at the beginning of the millennium.

The Clay Math Institute site has more on the PoincarÃ© Conjecture. Read about the rest of their Millennium Problems – 6 more problems each with a $1 million prize.
