ABSTRACT:

The paper addresses the challenge of constructing conforming
finite element spaces for high-order differential operators in high
dimensions, with a focus on the curl div operator in three
dimensions. Tangential-normal continuity is introduced in order to
develop distributional finite element curl div complexes. The spaces
constructed are applied to discretize a quad curl problem,
demonstrating optimal order of convergence. Furthermore, a
hybridization technique is proposed, demonstrating its equivalence to
nonconforming finite elements and weak Galerkin methods.
