Quasi Convex Integrands and Lower Semicontinuity in BV
Journal of convex analysis, Tome 8 (2001) no. 2, pp. 369-386
We discuss the lower semicontinuity of multiple integrals of the calculus of variations, for quasi convex integrands in BV setting. The main result is a lower semicontinuity theorem with respect to weak convergence in BV, i.e. L1-convergence of equi-BV sequences, under mild assumptions on the integrand. The approach we propose here is based on two main results:
