Convergence of dual ascent in non-convex/non-differentiable optimization
Fredrik Andersson, Marcus Carlsson, Carl Olsson
We revisit the classical dual ascent algorithm for minimization of convex functionals in the presence of linear constraints, and give convergence results which apply even for non-c…
Convex envelopes for fixed rank approximation
Fredrik Andersson, Marcus Carlsson, Carl Olsson
A convex envelope for the problem of finding the best approximation to a given matrix with a prescribed rank is constructed. This convex envelope allows the usage of traditional op…
On linear differential equations with infinitely many derivatives
Marcus Carlsson, Humberto Prado, Enrique G. Reyes
Differential equations with infinitely many derivatives, sometimes also referred to as ``nonlocal'' differential equations, appear frequently in branches of modern physics such as…
