The Ulm method is considered to approximate a solution of a nonlinear operator equation F(x) = 0. We study the convergence of this method when F(x) is ω-conditioned and prove that the R-order of convergence is at least 1 + p if ω is quasi-homogeneous of type ω(tz) ≤ t p ω(z), for z > 0, t ∈ [0,1] and p ∈ [0,1]. © 2008 Springer-Verlag.
