Convergence of products of matrices in projective spaces

Let Ak, be a sequence of n × n complex valued matrices which converge to a matrix A. If A and each Ak is positive then the product converges to a rank one matrix positive matrix uwT, where u is a positive column eigenvector of A. If each Ak is nonsingular and A has exactly one simple eigenvalue λ of the maximal modulus with the corresponding eigenvector u, then , converges to a rank one matrix uwT.
