Erdős Problems
Paul Erdős was a brilliant mathematician and one of the great problem posers of the twentieth century. Many of his problems had, and continue to have, a strong impact on research.
One of the ways that Paul would get people to work on his problems was by offering a reward to the person, or group, that first solved the problem. Many of these problems still remain open with values ranging from the few dollars to several thousand dollars.
The Combinatorics Foundation wants to encourage people to continue working on these problems and so will honor the rewards that Paul had offered, within reason.
In particular, the following must be done:
The reward must be documented in a publication of Paul's (no second-hand rumors, lectures, or other sources).
The solution must be confirmed and accepted by the mathematical community. At the very minimum this means that the solution must be published in a reputable, peer-reviewed journal in mathematics; and no previous solution has been published in a similar venue.
If you have met the above requirements and believe that you should receive one of Paul's rewards, then please contact Steve Butler (butler@iastate.edu) and include documentation to the two points above.
Disclaimer: There is no legal requirement by any individual or organization to honor the Erdős Problems. The Foundation can exercise discretion to award all, part, or none of an award as it sees fit. In some cases an award might be split as several key people were needed to be combined to solve the problem.
