ABSTRACT
A finite element T e on H n is a triplet (P , P, Γ) (see [3]) where E is a closed polyhedron in H n; P C CS(E), s € IN, is a finite dimensional space of real value functions (we shall assume that its dimension is M ); Γ is a set of linear functions 7 1 < i < M , linearly independent and defined over the set P. The set Γ is P-unisolvent (see [3,8]). In particular, there exist M functions Pi € P, 1 < i < M , such that 7j(p*) = 1 < i , j < M.
