Addendum to “An approximation result for special functions with bounded deformation” [J. Math. Pures Appl. (9) 83 (7) (2004) 929–954]: the N-dimensional case

Abstract We explain in this note how to adapt the proofs in our previous work: “An approximation result for special functions with bounded deformation” [J. Math. Pures Appl. (9) 83 (7) (2004)], to dimension higher than two.
