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…

A time adaptive optimal control approach for 4D-var data assimilation problems governed by parabolic PDEs
Carmen Gräßle, Jannis Marquardt
We interpret the 4D-var data assimilation problem for a parabolic partial differential equation (PDE) in the context of optimal control and revisit the process of deriving optimali…
