Schrödinger operators with oscillating potentials ∗
Schrödinger operators H with oscillating potentials such as cos x are considered. Such potentials are not relatively compact with respect to the free Hamiltonian. But we show that they do not change the essential spectrum. Moreover we derive upper bounds for negative eigenvalue sums of H.

Inequalities are derived for power sums of the real part and the modulus of the eigenvalues of a Schrödinger operator with a complexvalued potential.

متن کاملSchrödinger Operators with Complex-valued Potentials and No Resonances
In dimension d ≥ 3, we give examples of nontrivial, compactly supported, complex-valued potentials such that the associated Schrödinger operators have no resonances. If d = 2, we show that there are potentials with no resonances away from the origin. These Schrödinger operators are isophasal and have the same scattering phase as the Laplacian on R. In odd dimensions d ≥ 3 we study the fundament...
متن کاملPerturbation of a Fredholm Complex by Inessential Operators
The work of Ambrozie and Vasilescu on perturbations of Fredholm complexes is generalized by discussing the stability theory of Banach space complexes under inessential perturbations. 2000 Mathematics Subject Classification: Primary: 47A53; Secondary: 47A13.
متن کاملPerturbation of Complex Polynomials and Normal Operators
We study the regularity of the roots of complex monic polynomials P (t) of degree n depending smoothly on a real parameter t. If P (t) is C∞ and no two of the continuously chosen roots meet of infinite order of flatness, then there exists a locally absolutely continuous parameterization of the roots. Simple examples show that the conclusion is best possible. This result will follow from the pro...
