A note on a modification of Moser's method

We use a recurrence technique to obtain semilocal convergence results for Ulm's iterative method to approximate a solution of a nonlinear equation F (x) = 0fenced((x n + 1 = x n - B n F (x n),, n ≥ 0,; B n + 1 = 2 B n - B n F ′ (x n + 1) B n,, n ≥ 0 .))This method does not contain inverse opera...

Descripción
Sumario:We use a recurrence technique to obtain semilocal convergence results for Ulm's iterative method to approximate a solution of a nonlinear equation F (x) = 0fenced((x n + 1 = x n - B n F (x n),, n ≥ 0,; B n + 1 = 2 B n - B n F ′ (x n + 1) B n,, n ≥ 0 .))This method does not contain inverse operators in its expression and we prove it converges with the Newton rate. We also use this method to approximate a solution of integral equations of Fredholm-type. © 2007 Elsevier Inc. All rights reserved.
