Upper bounds for a class of energies containing a non-local term
ESAIM: Control, Optimisation and Calculus of Variations, Volume 16 (2010) no. 4, pp. 856-886.

In this paper we construct upper bounds for families of functionals of the form

E ε (φ):= Ω ε|φ| 2 + 1 ε W (φ)dx+1 ε N |H ¯ F(φ) | 2 dx
where Δ H ¯ u = div {χ Ω u}. Particular cases of such functionals arise in Micromagnetics. We also use our technique to construct upper bounds for functionals that appear in a variational formulation of the method of vanishing viscosity for conservation laws.
