Direct methods. An integral representation result
Andrea Braides, Anneliese Defranceschi · 1998
Abstract The direct methods of ┌-convergence for integral functionals consist in proving general abstract compactness results that assure the existence of ┌-converging sequences, and then in recovering enough information on the structure of the ┌-limits as to obtain a representation in a suitable form. For this purpose, it is useful to consider at the same time the dependence of the ┌-limits as set functions and as integrals.
