A primal finite element scheme of the Hodge Laplace problem
share
In this paper, a unified family, for any n⩾ 2 and 1⩽ k⩽ n-1, of nonconforming finite element schemes are presented for the primal weak formulation of the n-dimensional Hodge-Laplace equation on HΛ^k∩ H^*_0Λ^k and on the simplicial subdivisions of the domain. The finite element scheme possesses an 𝒪(h)-order convergence rate for sufficiently regular data, and an 𝒪(h^s)-order rate on any s-regular domain, 0<s⩽ 1, no matter what topology the domain has.
