On the Band Spectrum of a Schrodinger Operator in a Periodic System of Domains Coupled by Small Windows
Original language description
A periodic system of domains coupled by small windows is considered. In a domain of this kind, we study the band spectrum of a Schrodinger operator subjected to the Neumann condition. We show that, near every isolated eigenvalue of a similar operator inthe periodicity cell, there are several nonintersecting bands of the spectrum for the perturbed operator. We also discuss the position of points at which the band functions attain the edges of each band.
