Тема: Bethe–Sommerfeld property of periodic and almost-periodic Schrödinger operators: results old and new

Аннотация
I will give a survey of situations when we can establish a Bethe–Sommerfeld property (that all large energies belong to the spectrum) for multidimensional Schrödinger operators with periodic and almost-periodic potentials. While in the periodic setting the results are more than ten years old, there has been substantial recent activity in the almost-periodic case. In particular, I will describe my recent joint result with Yu.Karpeshina and R.Shterenberg.
