WebDec 16, 2024 · In this case, the eigenvalue of the matrix may be negative, but satisfies the Gershgorin circle theorem. Problem: What condition can be added to the Gershgorin theorem so that the eigenvalues localized with its help always lie only in the right half-plane, i.e. were only positive? This condition should also make it work in cases where the ...

WebDec 9, 2024 · 1 Answer. 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.
