| Dec 1, 2010 at 23:55 | comment | added | Igor Belegradek | More recent remarks on Hopf conjecture (about existence of positively curved metric on $S^2\times S^2$) can be found in the survey by Wilking: front.math.ucdavis.edu/0707.3091. This problem is somewhat poisoned as many talented people thought hard of it with little or no progress. | |
