Reduction of finite element subspace dimension based on estimated error

This paper examines the idea of basing dimensional reduction for finite element subspaces on estimated error. Orthonormal bases related to the error terms in a quadratic error estimator are established by solving algebraic eigenvalue problems, to identify components most suitable for deletion from f...
