A Variational Formulation of the BDF2 Method for Metric Gradient Flows
Daniel Matthes, Simon Plazotta
We propose a variational form of the BDF2 method as an alternative to the commonly used minimizing movement scheme for the time-discrete approximation of gradient flows in abstract…

High-frequency limit of non-autonomous gradient flows
Simon Plazotta, Jonathan Zinsl
We study the high-frequency limit of non-autonomous gradient flows in metric spaces of energy functionals comprising an explicitly time-dependent perturbation term which might osci…
