The Tunneling Effect for Schrödinger operators on a Vector Bundle

Markus Klein, Elke Rosenberger

In the semiclassical limit h to 0, we analyze a class of self-adjoint Schrödinger operators H_h = h^2 L + h W + V id_E acting on sections of a vector bundle E over an oriented Riem…

Harmonic Approximation of Difference Operators

Markus Klein, Elke Rosenberger

For a general class of difference operators $H_{ε} = T_{ε} + V_{ε}$ on $ℓ^{2} (ε Z^{d})$ , where $V_{ε}$ is a multi-well potential an…

Agmon-Type Estimates for a Class of Difference Operators

Markus Klein, Elke Rosenberger

We analyze a general class of self-adjoint difference operators $H_{ε} = T_{ε} + V_{ε}$ on $ℓ^{2} (ε Z^{d})$ , where $V_{ε}$ is a one…

Asymptotic Eigenfunctions for a class of Difference Operators

Markus Klein, Elke Rosenberger

We analyze a general class of difference operators $H_{ε} = T_{ε} + V_{ε}$ on $ℓ^{2} (ε Z^{d})$ , where $V_{ε}$ is a one-well potent…
