For reference: Gershgorin circle theorem. The eigenvalues ˜λk of ˜A are really at the distance of not more than ∑nj = 1 eij from the eigenvalues λi of A. (Note as A is diagonal, its diagonal elements are precisely aii = λi .) This inequality enables us to uniquely map the eigenvalues λi of A to the eigenvalues ˜λi of ˜A. i hope you have a good health https://baileylicensing.com
