- W2964307381 abstract "We present new results concerning the approximation of the total variation, $$int _{Omega } |nabla u|$$ , of a function u by non-local, non-convex functionals of the form $$begin{aligned} Lambda _delta (u) = int _{Omega } int _{Omega } frac{delta varphi big ( |u(x) - u(y)|/ delta big )}{|x - y|^{d+1}} , dx , dy, end{aligned}$$ as $$delta rightarrow 0$$ , where $$Omega $$ is a domain in $$mathbb {R}^d$$ and $$varphi : [0, + infty ) rightarrow [0, + infty )$$ is a non-decreasing function satisfying some appropriate conditions. The mode of convergence is extremely delicate and numerous problems remain open. De Giorgi’s concept of $$Gamma $$ -convergence illuminates the situation, but also introduces mysterious novelties. The original motivation of our work comes from Image Processing." @default.
