Electronic Journal of Differential Equations, Vol. 2007(2007), No. 124, pp. 1-13. Title: Newton's method in the context of gradients Authors: Janos Karatson (ELTE Univ., Budapest, Hungary) John W. Neuberger (Univ. of North Texas, Denton, TX, USA) Abstract: This paper gives a common theoretical treatment for gradient and Newton type methods for general classes of problems. First, for Euler-Lagrange equations Newton's method is characterized as an (asymptotically) optimal variable steepest descent method. Second, Sobolev gradient type minimization is developed for general problems using a continuous Newton method which takes into account a "boundary condition" operator. Submitted August 8, 2005.
