I saw few questions about it, but still can't understand.
Let A be a symmetric matrix and λmax its largest eigenvalue. Is the following true for all A?
\lambda_{\max} \ge a_{ii} \forall i
That is, is the largest eigenvalue of a symmetric matrix always greater than any of its diagonal entries?
Is it somehow related to spectral radius and the following equation?
\rho(A)=\max|\lambda_i|.
