In this paper, we construct, in a unified fashion, lower order finite element subspaces of spaces of symmetric tensors with square-integrable divergence on a domain in any dimension. These subspaces are essentially the symmetric tensor finite element spaces of order k from [Finite element approximations of symmetric tensors on simplicial grids in Rn: The higher order case, J. Comput. Math. 33 (2015) 283–296], enriched, for each (n − 1)-dimensional simplex, by (n+1)n 2 face bubble functions in… CONTINUE READING
