| contents | We design a discrete Bernstein--Gelfand--Gelfand (BGG) diagram on polygonal meshes based on the DDR framework; the diagram is made of a discrete Stokes polygonal complex and a tensorised Discrete De Rham complex, and the BGG construction leads to a novel elasticity complex applicable on generic polygonal meshes. Complete homological and analytical properties of the discrete Stokes complex are established, including primal and adjoint consistency estimates as well as Poincaré inequalities. Homological properties of the complexes built from the BGG diagram are also established. |
