Abstract:

A finite difference technique on rectangular cell-centered grids with local refinement is proposed in order to derive discretizations of second-order elliptic equations of divergence type approximating the so-called balance equation. Error estimates in a discrete ${H^1}$-norm are derived of order ${h^{1/2}}$ for a simple symmetric scheme, and of order ${h^{3/2}}$ for both a nonsymmetric and a more accurate symmetric one, provided that the solution belongs to ${H^{1 + \alpha }}$ for $\alpha > \frac {1}{2}$ and $\alpha > \frac {3}{2}$, respectively.
