Conférence - DimaScat : Théorie du scattering et asymptotiques spectrales d'opérateurs différentiels - en l'honneur de Dimitri Yafaev
We consider the multi-dimensional Schrödinger operator with a bounded periodic potential. We show that in the 2D case the corresponding band functions can attain their extrema only at a finite number of points.
This is a joint work with I. Kachkovskiy.
