Mixed finite elements on sparse grids
Copyright policy )Mixed finite elements on sparse grids
The authors are concerned with the construction of discrete differential forms of lowest order on regular sparse grids. They analyse fairly rigorously their approximation properties and find accurate and computable approximations for nodal interpolation operators.
