Superconvergence of linear finite elements on simplicial meshes
In this dissertation work, we present a theoretical analysis for linear finite element gradient superconvergence on three-dimensional simplicial meshes where the lengthes of each pair of opposite edges in most tetrahedrons differ only by $O(h^{1+\alpha})$. We first derive a local error expansion for...
