A new approximation result for BV-functions
[Un nouveau résultat d'approximation pour fonctions BV]
Comptes Rendus. Mathématique, Volume 340 (2005) no. 10, pp. 735-738.

On démontre un théorème de approximation pour une fonction qui appartient à l'espace BV avec une suite quasi-polyédriques de fonctions BV. Cette approximation peut être très utile pour quelques problèmes du Calcul des Variations.

This Note is devoted to obtaining an approximation result for BV-functions by means of a quasi-polyhedral sequence of BV-functions. This approximation could have interesting applications in some problems of the Calculus of Variations.
