| Abstract: | We prove a criterion for absence of decaying solutions for one-dimensional Schrödinger operators. As necessary input, we require infinitely many centers of local reflection symmetry and upper and lower bounds for the traces of the associated transfer matrices. |
| Keywords: | Schr" odinger operators, eigenvalue problem, local reflection symmetries |
