A $prox$ -Based Semi-Smooth Newton Method for TV-Minimization

Sören Bartels, Alex Kaltenbach

In this paper, we devise a $prox$ -based semi-smooth Newton method for the non-differentiable TV-minimization problem. To this end, the primal-dual optimality conditi…

Variational problems with gradient constraints: $A priori$ and $a posteriori$ error identities

Harbir Antil, Sören Bartels, Alex Kaltenbach +1

In this paper, on the basis of a (Fenchel) duality theory on the continuous level, we derive an $a posteriori$ error identity for arbitrary conforming approximations of a…
