Perturbation theory for spectral gap edges of 2D periodic Schr\"odinger operators

28 Apr 2017 Parnovski Leonid Shterenberg Roman

We consider a two-dimensional periodic Schr\"odinger operator $H=-\Delta+W$ with $\Gamma$ being the lattice of periods. We investigate the structure of the edges of open gaps in the spectrum of $H$... (read more)
