Abstract:
On the plane, the operator $-\mathrm {div} (g(x)\nabla \cdot )+V(x)$ is considered. The absolute continuity of its spectrum is proved under the assumption that each coefficient is the sum of a $\mathbb {Z}^2$-periodic term and a summand that is periodic in one of the variables and decays superexponentially with respect to the other variable.References
