Finite-Volume-Element Method for Second-Order Quasilinear Elliptic Problems [link]Paper  doi  abstract   bibtex   
In this paper we consider the finite-volume-element method for general second-order quasilinear elliptic problems over a convex polygonal domain in the plane. Using reasonable assumptions, we show the existence and uniqueness of the finite-volume-element approximations. It is proved that the finite-volume-element approximations are convergent with Graphic, where r > 2, and Graphic in the H1-, W1, �- and L2-norms, respectively, for u ? W2, r(�) and u ? W2, �(�) ? W3, p(�), where p > 1. Moreover, the optimal-order error estimates in the W1, �- and L2-norms and an Graphic estimate in the L�-norm are derived under the assumption that u ? W2, �(�) ? H3(�). Numerical experiments are presented to confirm the estimates.
