Dörfler, Willy

SIAM J. Numer. Anal. 33, No. 3, 1106-1124 (1996).

The authors develop a convergent adaptive algorithm for linear elements applied to Poisson’s equation in two space dimension. Existence and uniqueness of the problem are illustrated by examples. Extensions are made to higher-order elements in two space dimensions and numerical results are included.
