Résumé
We study the minimization of functionals of the form
with a convex integrand
After a short introduction to the problem I want to focus on the question of regularity of BV minimizers. In past years, Sobolev regularity was established provided that the lack of ellipticity — which is always inherent for such linear growth integrands — is mild, while, in general, only some structure results seems to be within reach. In this regard, I will review several results which were obtained in cooperation with Miroslav Bulíček (Prague), Franz Gmeineder (Konstanz), Erika Maringová (Vienna), and Thomas Schmidt (Hamburg).
