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
