Dimensional Properties for the Spectra of Sturmian Hamiltonians in a Small Coupling Regime

Alexandro Luna (UCI)

Abstract: We prove that the Hausdorff dimension of the spectrum of a Sturmian Hamiltonian of bounded type tends to one as the coupling constant tends to zero. We give a sketch of the proof which...

Scalar curvature along Ebin geodesics

Christoph Böhm (Münster)

Let \(M^n\) be a smooth, compact manifold and let \(N\) denote the set of Riemannian metrics on \(M^n\) with a fixed smooth volume density \(\mu\) of volume 1. For any \(g_0 \in N\) , we show that...
