Anisotropic free-discontinuity functionals as the Γ-limit of second-order elliptic functionals
We provide an approximation result for free-discontinuity functionals of the form 𝓕(u) = ∫Ωf(x, u, ∇u)dx + ∫Su∩Ωθ(x, νu)d𝓗n−1, u ∈ SBV2(Ω), where f is quadratic in the gradient-variable and θ is an arbitrary smooth Finsler metric. The approximating functionals are of Ambrosio-Tortorelli...
