, 2007 In this paper we propose a new a--posteriori error estimator for a weakly singular integral equation concerned with a direct boundary element approach for a Dirichlet problem with a second order elliptic partial differential operator. The method is based

The hat matrix for smoothing splines
The matrix which transforms the data vector to the vector of fitted values for smoothing splines is termed the hat matrix. This matrix is shown to have many of the same properties, and is seen to play the same role in the variances and covariances of the

Dimension and Local Bases of Homogeneous Spline Spaces
, 1995 . Recently, we have introduced spaces of splines defined on triangulations lying on the sphere or on sphere-like surfaces. These spaces arose out of a new kind of Bernstein-B'ezier theory on such surfaces.

B–SPLINE–BASED MONOTONE MULTIGRID METHODS — EXTENDED VERSION ∗
, 2008 . For the efficient numerical solution of elliptic variational inequalities on closed convex sets, multigrid methods based on piecewise linear finite elements have been investigated over the past decades.
