摘要：

We prove a super approximation result for a wide class of approximation spaces (including finite elements and wavelet type spaces). In particular such property, also referred at as the discrete commutator property holds, provided that a projector operator exists, who acts "locally". Such property is used in getting estimates through localization techniques ([3], [4], [6], [5]). (C) 1999 Academie des sciences/Editions scientifiques et medicales Elsevier SAS.
