摘要：
The paper presents a box scheme with quadratic basis functions for the discretisation of elliptic boundary value problems. The resulting discretisation matrix is non-symmetrical (and also not an M-matrix). The stability analysis is based on an elementwise estimation of the scalar product [A(h) u(h), u(h)]. Sufficient conditions placed on the triangles of the triangulation lead to discrete ellipticity. Proof of an O(h(2)) error estimate is given for these conditions.
