Add a comment. 2. If λ is a characteristic root of A, there is x ≠ 0 such that A x = λ x. We thus have A 2 x = A ( λ x) = λ A x = λ 2 x, and by induction over p, A p x = λ p x for each positive integer p. In particular, for p = n, we get A n x = λ n x, hence x = λ n x. Since x ≠ 0, λ is necessarily a n th root of unity.
WebIn linear algebra, a characteristic polynomial of a square matrix is defined as a polynomial that contains the eigenvalues as roots and is invariant under matrix similarity. The characteristic equation is the equation derived by equating the characteristic polynomial to zero. It is also known as the determinantal equation.
In linear algebra, the characteristic polynomial of a square matrix is a polynomial which is invariant under matrix similarity and has the eigenvalues as roots. It has the determinant and the trace of the matrix among its coefficients.
