3 апр. 2018 г. · I am unable to see that the norm must be less than or equal to the maximum eigenvalue of A: ||A||≤ max λ∈σ(A) λ.

6 мар. 2016 г. · Let λ be an eigenvalue of Q. Let ρ(Q) be the spectral norm of Q, which is the absolute value of the largest eigenvalue: ρ(Q)≜|λmax(Q)|.

12 июл. 2020 г. · In this definition, the operator norm is the the absolute value of the largest eigenvalue. since A is symmetric.

19 июл. 2017 г. · If I'm not mistaken, the operator norm of a matrix is the square root of the largest eigenvalue. I'm a bit confused as to what ‖φ1‖≠‖ ...

2 июн. 2015 г. · The matrix norm associated to the Euclidean norm is ‖A‖=λmax(A∗A). So, this is about the eigenvalues of A∗A, not A. In the example by littleO we ...
