Unsolved problems in mathematics in the field of number theory.

Hadwiger's name is also associated with several important unsolved problems in mathematics:

Hilbert posed twenty-three then unsolved problems in mathematics which he believed were of the most immediate importance.

A Russian mathematician is reporting that he has proved the Poincaré Conjecture, one of the most famous unsolved problems in mathematics.

He was responsible for formulating the Poincaré conjecture, which was one of the most famous unsolved problems in mathematics until it was solved in 2002-2003.

In a 1900 speech to the International Congress of Mathematicians, David Hilbert set out a list of 23 unsolved problems in mathematics.

His website Links to unsolved problems, prizes and research is top ranked by Google for list of unsolved problems in mathematics and physics.

Smale's problems are a list of eighteen unsolved problems in mathematics that was proposed by Steve Smale in 1998, republished in 1999.

The Riemann hypothesis, one of the most important unsolved problems in mathematics, concerns the location of the zeros of the Riemann zeta function.

One of the important unsolved problems in mathematics is the description of the unitary dual, the effective classification of irreducible unitary representations of all real reductive Lie groups.

His contributions to pure and applied mathematics, mathematical physics led him to formulating the Poincare conjecture, one of the most famous unsolved problems in mathematics until it was solved by Perlemen in 2003.

SCIENCE TIMES, PAGE F1 Three-Dimensional Proof A Russian mathematician, Dr. Grigori Perelman, has offered a solution to the Poincaré Conjecture, one of the most famous unsolved problems in mathematics.

The Riemann hypothesis, first tossed off by Bernhard Riemann in 1859 in a paper about the distribution of prime numbers, is still widely considered to be one of the greatest unsolved problems in mathematics, sure to wreath its conqueror with glory - and, incidentally, lots of cash.
