Long- and short-time behavior of hypocoercive evolution equations with higher index via modal decompositions
Marco Roschkowski, Hannes Gernandt
Hypocoercivity emerged in kinetic transport theory, allowing to derive exponential long-time estimates for evolution equations. Recently, the short-time asymptotics for equations w…

Two energy methods for distributed port-Hamiltonian systems and their application to stability analysis
Marco Roschkowski, Hannes Gernandt
We develop two local energy methods for distributed parameter port-Hamiltonian (pH) systems on one-dimensional spatial domains. The methods are applied to derive a characterization…

Improving Robustness of Foundation Models in Domain Adaptation with Soup-Adapters
Marco Roschkowski
In this paper, we tackle two fundamental problems in few-shot domain adaptation of foundation models. First, hyperparameter tuning is often impractical due to the lack of large val…
