Complete representation of some functionals showing the Lavrentieff phenomenon

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2001
The functional F(u) = ∫Bf(x, Du) is considered, where B is the unit ball in R2, u varies in the set of the locally Lipschitz functions on R2 and f belongs to a family containing, as model case, the following integrand: The computation of the relaxed functional F̄ is provided yielding an explicit representation formula.This formula nevertheless is not ...

Lavrentieff phenomenon and non standard growth conditions

2001
In the paper the functional \[ F(u)= \int_B f(x,Du) dx \] is considered, where \(B\) is the unit ball in \(\mathbb{R}^n\) and \(u\) varies among Lipschitz functions. The integrand \(f\) belongs to a family containing, as a model case, the function \[ f(x,z)= {|z\cdot x|\over|x|^n}+|z|^p\quad\text{with }1< p< n.
