Stability of Lagrange elements for the mixed Laplacian
The stability properties of simple element choices for the mixed formulation of the Laplacian are investigated numerically. The element choices studied use vector Lagrange elements, i.e., the space of continuous piecewise polynomial vector fields of degree at most r , for the vector variable, and the divergence of this space, which consists of discontinuous piecewise polynomials of one degree l...
