Partial Observation of Linear Systems with the Mori-Zwanzig Formalism
Fan Wang, Peter Benner, Jan Heiland
The Mori-Zwanzig formalism provides a systematic framework for deriving reduced-order model of dynamical systems when only part of the state is observed, but its practical use is o…

A-priori error estimation for space-time Galerkin POD for linear evolution problems
Carmen Gräßle, Jan Heiland, Jannis Marquardt
In this paper, we propose an a-priori error estimate for the model order reduction (MOR) method of space-time proper orthogonal decomposition (space-time POD). The original space-t…
