A primal finite element scheme of the $\mathbf{H}(\mathbf{d})\cap \mathbf{H}(\boldsymbol{\delta})$ elliptic problem

In this paper, a unified family, for $n\geqslant2$ and $1\leqslant k \leqslant n-1$, of finite element schemes are presented for the primal weak formulation of the $n$-dimensional $H(\mathbf{d}^k)\cap H(\boldsymbol{\delta}_k)$ elliptic problem.
