Let $V_h$ be the continuous piecewise-polynomial velocity space of degree $4$ on the structured Freudenthal tetrahedral meshes, and let $\Sigma_h$ denote the associated potential s…

Let $V_h\subset[H^1(\Omega)]^3$ be constructed with continuous Lagrange elements of degree $k$. Let $\Sigma_h\subset H^1(\operatorname{curl},\Omega)$ be the space preceding $V_h$ i…
