| Abstract: | The absence of eigenvalues (of infinite multiplicity) for the two-dimensional periodic Schrödinger operator with a variable metric is proved. The method of proof does not use the change of variables reducing the metric to a scalar form. |
| Keywords: | Schrö dinger operator spectrum periodic electric potential periodic magnetic potential variable metric |
