Eigenvalues of an inverse matrix
WebA matrix A has an eigenvalue λ if and only if A − 1 has eigenvalue λ − 1. To see this, note that. A v = λ v A − 1 A v = λ A − 1 v A − 1 v = 1 λ v. If your matrix A has eigenvalue λ, then I − A has eigenvalue 1 − λ and therefore ( I − A) − 1 has eigenvalue 1 1 − λ. Share.
