Partial Convergence and Sign Convergence of Matrix Powers via Eigen c--ads Frank Uhlig This paper investigates the convergence over the reals and in the sign +, -, 0 sense of individual elements of matrix powers of A (A to the power k, as k tends to infinity) in dependence on the eigenvalues and left and right (generalized) eigenvector structure of a given n by n matrix A theoretically and computationally.
