| Jan 12, 2015 at 20:27 | comment | added | Jiao Guo | @ChrisGodsil it just means that if you take the upper (n-1)x(n-1) submatrix of $A$, then the eigenvalues between this matrix and $A$ are interlacing. So between any eigenvalues of $A$ is one of the submatrix, but I guess that this property is more or less unrelated to this question. | |
