On the structure of the edges of spectral bands of the periodic Schrödinger operator
Résumé: 

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.
