Abstract

A unified construction of the Hm-nonconforming virtual elements of any order k is developed on any shape of polytope in Rn with constraints m ≤ n and k ≥ m. As a vital tool in the construction, a generalized Green's identity for Hm inner product is derived. The Hm-nonconforming virtual element methods are then used to approximate solutions of the m-harmonic equation. After establishing a bound on the jump related to the weak continuity, the optimal error estimate of the canonical interpolation, and the norm equivalence of the stabilization term, the optimal error estimates are derived for the Hm-nonconforming virtual element methods.
