Abs-Smooth Frank-Wolfe method for convex functions
The Abs-Smooth Frank-Wolfe algorithm (ASFW) is a non-smooth variant of the popular Frank-Wolfe algorithms. In this talk we sketch and analyze the "vanilla" and the "heavy-ball" variants of the ASFW algorithm. We provide stronger and more general primal-dual convergence results for ASFW when applied in the convex setting. We derive a convergence rate for our algorithm which is identical to the smooth case. So far, there is limited understanding of accelerated convergence regimes in the context of ASFW. We also provide some answers in this context by looking into some special cases. |

Finsler geodesics and finite-strain plasticity
The theory of energetic rate-independent systems is an elegant way to describe nonlinear systems in mechanics and other fields. One particular advantage is that it yields a natural time discretization that consists of a sequence of minimization problems. Unfortunately, in many interesting cases the objective functional is only given implicitly as the solution of a second minimization problem for a |
