,On the ratio of the first two eigenvalues of Schrödinger operators with positive potentials,et boundary conditions and non-negative potentials. We discuss the Payne-Pólya-Weinberger conjecture for H.=−Δ and generalize the conjecture to Schrödinger operators. Lastly, we present our recent result giving the best possible upper bound λ./λ.≤4 for one-dimensional Schrödinger operators with nonn

Existence and finite-dimensionality of attractors for the Landau-Lifschitz equations, for the understanding of nonequilibrium magnetism. We sketch a proof that, under quite general conditions, dissipative forms of these equations have attracting sets which are finite-dimensional in a suitable sense. In particular, upper bounds are obtained for the Hausdorff and fractal dimensions of

Der Aufbau der Jugendstudie StaufenDie Jugendstudie Staufen war von Beginn so angelegt, dass man sich dem zentralen Thema „Freizeitmöglichkeiten von Jugendlichen in Staufen“ aus verschiedenen Blickwinkeln nähern wollte.
