Modified deflation algorithm for the solution of singular problems. I. A system of nonlinear algebraic equations
Abstract The Behavior of the Newton-Raphson method at the singular roots has been studied by a number of authors and the convergence of the Newton-Raphson sequence has been shown to be linear. InExpand
