Abstract
This paper deals with variational problems which have among the unknowns an hypersurface. In order to deal with these problems, it has been introduced in [15] the space SBV(Ω) of “special” functions with bounded variation. By summarizing the results of [2] and [4], we recall here the definition and the main compactness properties of SBV(Ω). In addition, we state lower semicontinuity criteria for integral functionals defined in SBV(Ω). Finally, we show how these variational problems can be approximated by others, more tractable from the numerical point of view.
