Abstract
The solution of the fourth order problem bounded in , and its Laplacian are approximated by polynomial finite elements of the same degree,. It is shown that in any subdomain the approximation to converges with ‘nearly’ the same order as the approximiation to u does provided u is sufficiently regular.Keywords
