On the convergence of the cyclic and quasi-cyclic block Jacobi methods

We study a general block Jacobi-type method under several classes of cyclic and quasi-cyclic strategies and prove simple conditions under which this method converges to the diagonal form. The new results can be applied to Jacobi-type processes for ordinary and generalized eigenvalue problems.
