چکیده
We prove a semicontinuity theorem for an integral functional made up by a polyconvex energy and a surface term. Our result extends to the BV framework a well known result by John Ball.

Weak Lower Semicontinuity for Polyconvex Integrals in the Limit Case
We prove a lower semicontinuity result for polyconvex functionals of the Calculus of Variations along sequences of maps u : Ω ⊂ R → R in W , 2 ≤ m ≤ n, bounded in W 1,m−1 and convergent in L under mild technical conditions but without any extra coercivity assumption on the integrand.
متن کاملLower Semicontinuity of Quasi-convex Bulk Energies in SBV and Integral Representation in Dimension Reduction
A result of Larsen concerning the structure of the approximate gradient of certain sequences of functions with Bounded Variation is used to present a short proof of Ambrosio’s lower semicontinuity theorem for quasiconvex bulk energies in SBV . It enables to generalize to the SBV setting the decomposition lemma for scaled gradients in dimension reduction and also to show that, from the point of ...
