Abstract
We consider a nonlinear second-order elliptic boundary value problem in a bounded domain $\Omega \subset \mathbb{R}^N$ with mixed boundary conditions. The solution is found via linearisation. We design a robust and efficient approximation scheme. Error estimates for the linearisation algorithm are derived in $L_2(\Omega)$, $H^1(\Omega)$ and $L_{\infty}(\Omega)$ spaces under the minimal regularity assumptions of the exact solution.
