Explicit Planar Finite Element Elasticity Complexes and $C^1$ Elements on Barycentric Refinements
Explicit closed-form enrichments and Airy potentials yield a concrete Hsieh-Clough-Tocher-type C^1 space whose image is exactly the Arnold-Douglas-Gupta stress space, enabling global explicit elasticity complexes and new C^1 elements on barycentric refinements.
