Abstract:

The purpose of this paper is to find pointwise representation formulas for the density of the pairing between divergence-measure fields and BV functions, in this way continuing the research started in Anzellotti's pairing theory and Pairings between bounded divergence-measure vector fields and $BV$ functions. In particular, we extend a representation formula from an unpublished paper of Anzellotti involving the limit of cylindrical averages for normal traces, and we exploit a result of Šilhavý in order to derive another representation in terms of limits of averages in half balls.

Keywords: Gauss-Green formula, divergence-measure fields, normal traces
