Abstract :
Iterative methods applied to eigenvalue equations can lead to anomalous convergence. It is shown that this can occur when some of the eigenvalues are complex and the corresponding eigenvectors satisfy a particular condition. A method of distinguishing between anomalous and effective convergence is indicated.
