Explanation of a proof of an determinant bound?
It is not clear how you get \begin{eqnarray*} (x_2^TAx_2)(x_2^TA^{-1}x_2) &\le& \frac{(\lambda_2 + \lambda_{n-1})^2}{4\lambda_2\lambda_{n-1}}. \end{eqnarray*} |

Eigenspace of Euclidean distance matrix.
+1, Thanks, I know this fact. Do you think if it is possible to characterize the orthogonal matrix $P$ such that $P^TMP$ is diagonal? |
