Relaxation in BV×Lp
 
 
Description: 

An integral representation result is obtained for the relaxation of a class of energy functionals depending on two vector fields u in BV and v in Lp with 1<p≤+∞. This energy have been introduced to deal with equilibria for systems depending on chemical composition and elastic strain.

In this work we add the dependence on the spatial variable x and the deformation u to the functional. Also the quasiconvexity assumption is dropped.

This result may also find applications in the framework of image decomposition models.  This is a joint work with Elvira Zappale.
