ABSTRACT="
We consider a finite volume discretization of second-order non-linear elliptic boundary value problems on polygonal domains. Using relatively standard assumptions we show the existence of the finite volume solution. Furthermore, for a sufficiently small data the uniqueness of the finite volume solution may also be deduced. We derive error estimates in <i>H</i><sup>1</sup>-, <i>L</i><sub>2</sub>- and <i>L</i><sub>\infinity</sub>-norm for small data and convergence in <i>H</i><sup>1</sup>-norm for large data. In addition a Newton's method is analysed for the approximation of the finite volume solution and numerical experiments are presented.
