Abstract: The behavior of the vector recurrence is studied under very weak assumptions. Let denote the spectral radius of *M* and let . Then if the are bounded in norm and a certain subspace hypothesis holds, the root order of the is shown to be . If one additional hypothesis on the dimension of the principal Jordan blocks of *M* holds, then the quotient order of the is also . The behavior of the homogeneous recurrence is studied for all values of .

These results are applied to the analysis of

(1) Nonlinear iteration with application to iteration with memory and to parallel iteration algorithms.

(2) Order and efficiency of composite iteration.
