Repeating eigenvalues.

Repeated Eigenvalues Repeated Eigenvalues In a n×n, constant-coefficient, linear system there are two possibilities for an eigenvalue λof multiplicity 2. 1 λhas two linearly independent eigenvectors K1 and K2. 2 λhas a single eigenvector Kassociated to it. In the first case, there are linearly independent solutions K1eλt and K2eλt.

If they are numeric, eigenvalues are sorted in order of decreasing absolute value. Non-diagonalizable matrices with a repeated eigenvalue. Theorem (Repeated eigenvalue) If λ is an eigenvalue of an n × n matrix A having algebraic multiplicity r = 2 and only one associated eigen-direction, then the differential equation x0(t) = Ax(t), has a linearly independent set of solutions given by x(1)(t) = v eλt, x(2)(t) = v t + w eλt.

The first step is to form K with the repeated eigenvalue inserted. Then, the rank of K is determined and it is found that the number of linearly independent eigenvectors associated with the repeated eigenvalue will be equal to the difference between the order of K and the rank of A, that is, n ? r.
