Abstract: | We consider Newton-like methods for the solution of quasilinear elliptic boundary value problems. The quasilinear problems
are linearized by a Newton-method and the linear problems are approximately solved by a spectral projection method (e.g.,
the Ritz-Galerkin or the collocation method). convergence results are derived that show the spectral accuracy of this method.
The results are of a local type which means that we assume the starting approximation to be sufficiently near to the exact
solution. |
