| Apr 21, 2013 at 19:29 | comment | added | Carlo Beenakker | the information is just not there, no amount of math can help you. | |
| Apr 21, 2013 at 18:46 | comment | added | majid arezoomand | We can suppose that the eigenspaces of eigenvalues of $A^2$ are available. | |
| Apr 21, 2013 at 18:44 | comment | added | majid arezoomand | Ok. But I want a general result. Not for speciall graphs. Indeed I am looking for any result or paper concerning this problem. | |
| Apr 21, 2013 at 18:43 | comment | added | Carlo Beenakker | how would $A^2$ contain that information? | |
| Apr 21, 2013 at 18:41 | comment | added | Alireza Abdollahi | If $\Gamma$ is bipartite then both $\lambda$ and $-\lambda$ are eigenvalues of $\Gamma$. | |
