In this paper we develop an adaptive procedure for the numerical solution of general, semilinear elliptic problems with possible singular perturbations. Our approach combines both prediction-type adaptive Newton methods and a linear adaptive finite element discretization (based on a robust a posteriori error analysis), thereby leading to a fully adaptive Newton–Galerkin scheme. Numerical experiments underline the robustness and reliability of the proposed approach for various examples

We derive a torsionfull version of three-dimensional N=2 Newton-Cartan supergravity using a non-relativistic notion of the superconformal tensor calculus. The “superconformal” theory that we start with is Schrödinger supergravity which we obtain by gauging the Schrödinger superalgebra. We present two non-relativistic N=2 matter multiplets that can be used as compensators in the superconformal calculus. They lead to two different off-shell formulations which, in analogy with the relativistic case, we call “old minimal” and “new minimal” Newton-Cartan supergravity. We find similarities but also point out some differences with respect to the relativistic case.

Welsch (Projektbearbeiter): Heftige Kritik an dem Verfassungsentwurf des Ministeriums Camphausen (erste Kammer als "Waffenkammer vor de Reaction", keine direkten Wahlen, keine Versammlungsfreiheit): "Mir hat mein Verstand stille gestanden, wie ich hab Ihren Entworf gelesen, wie muß er erst Ihnen haben stille gestanden, wie Sie ihn haben geschrieben!" Prophezeiung des baldigen Rücktritts des Ministeriums

Welsch (Projektbearbeiter): Bemängelung der personellen Kontinuität in den aufeinanderfolgenden Kabinetten Camphausen und Auerswald (Finanzminister Hansemann) sowie der allzu raschen Stellung der Vertrauensfrage an die Preußische Nationalversammlung. Lob für die Anerkennung der Revolution
