Dispersive estimates for Schrödinger operators lie at the heart of contemporary analysis in quantum mechanics and partial differential equations. These estimates characterise the decay of solutions ...

The general subject of the talk is spectral theory of discrete (tight-binding) Schrodinger operators on $d$-dimensional lattices. For operators with periodic ...

We study decaying oscillatory perturbations of periodic Schrödinger operators on the half line. More precisely, the perturbations we consider satisfy a generalized bounded variation condition at ...
