An ultra-weak space-time variational formulation for the Schrödinger equation Open
We present a well-posed ultra-weak space-time variational formulation for the time-dependent version of the linear Schrödinger equation with an instationary Hamiltonian. We prove optimal inf-sup stability and introduce a space-time Petrov-…

Reviews and syntheses: A framework to observe, understand and project ecosystem response to environmental change in the East Antarctic Southern Ocean Open
Systematic long-term studies on ecosystem dynamics are largely lacking from the East Antarctic Southern Ocean, although it is well recognized that they are indispensable to identify the ecological impacts and risks of environmental change.…

Planning marine protected areas under the CCAMLR regime – The case of the Weddell Sea (Antarctica) Open
Currently, almost 8% of the world’s oceans are designated marine protected areas (MPAs), the majority of which
\nare relatively small and under national jurisdiction. Several initiatives are presently underway in international
\nwaters to …

Evaluation of the achievement of WSMPA conservation features and their target values for WSMPA Phase 1 Open
At CCAMLR-38, the Delegation of the European Union and its Member States and Norway proposed that the Weddell Sea Marine Protected Area (WSMPA) should be adopted by CCAMLR in two phases: WSMPA Phase 1 and WSMPA Phase 2. A proposal to estab…

A Hierarchical A-Posteriori Error Estimator for the Reduced Basis Method Open
We present an online-efficient hierarchical a-posteriori error estimator for the Reduced Basis Method (RBM), which uses the difference of two reduced approximations of different accuracy to estimate the true error of a reduced approximatio…

A Hierarchical A-Posteriori Error Estimatorfor the Reduced Basis Method Open
In this contribution we are concerned with tight a posteriori error estimation for projection based model order reduction of $\inf$-$\sup$ stable parameterized variational problems. In particular, we consider the Reduced Basis Method in a …
