Sep 30, 2010 at 2:08 | comment | added | S. Carnahan♦ | I do not think MathOverflow should become the go-to place for evaluating other people's mathematical claims (especially if said people have made additional bold claims concerning the Goldbach conjecture and Fermat's last theorem with no evidence of prior mathematical work in that area). I encourage votes to close, and am contemplating deletion. | |
