Abstract
We describe a hierarchical basis for the p-version of the finite element me thod in two and three dimensions. The corresponding stiffness matrices are shown to have good sparsity properties and better conditioning than those g enerated from existing hierarchical bases. (C) 2001 Elsevier Science B.V.
