Summary LetΦ: ℂ n →ℂ n be Fréchet differentiable, and let the equation (1) $$x = \Phi \left( x \right)$$ have at least one fixed point. We considerk-step stationary iterative methods (2) $$y_m : = \mu _0 \Phi \left( {y_{m - 1} } \right) + \mu _1 y_{m - 1} + ... + \mu _k y_{m - k} , m \geqq k,$$ withμ 0+μ 1+...+μ k =1. Using results for an affine mappingΦ: ℂ n →ℂ n , it is proven that (2) may converge locally even in cases where the usual iterationx m =Φ(x m−1) belonging to (1) diverges. These results are extended to nonstationary methods of type (2) and to “cyclic” mappings.
