Journal of Convex Analysis 31 (2024), No. 2, 411--476 Copyright Heldermann Verlag 2024 Γ-Convergence and Integral Representation for a Class of Free Discontinuity Functionals Gianni Dal Maso SISSA, Trieste, Italy dalmaso@sissa.it Rodica Toader (1) Dept. of Mathematics, Informatics and Geosciences, University of Trieste, Trieste, Italy (2) D.M.I.F., Università di Udine, Udine, Italy rodica.toader@units.it We study the Γ-limits of sequences of free discontinuity functionals with linear growth, assuming that the surface energy density is bounded. We determine the relevant properties of the Γ-limit, which lead to an integral representation result by means of integrands obtained by solving some auxiliary minimum problems on small cubes. Keywords: Free discontinuity problems, Gamma-convergence, integral representation, blow-up method. MSC: 49J45, 49Q20, 74Q05, 74E30. [ Fulltext-pdf (385 KB)] for subscribers only. |
