| Mar 7, 2010 at 22:46 | comment | added | Igor Pak | Actually, sometimes people do try hard, but the problem happens to be too difficult. I am thinking of this paper tinyurl.com/y8nm544 which claims that a very elegant combinatorial complex is in fact a Grassmannian. This problem proved to be very difficult indeed, and if I understand things correctly, still unresolved. | |
