چکیده

We introduce a novel approach for defining a δ′-interaction on a subset of the real line of Lebesgue measure zero which is based on Sturm– Liouville differential expression with measure coefficients. This enables us to establish basic spectral properties (e.g., self-adjointness, lower semiboundedness and spectral asymptotics) of Hamiltonians with δ′-interactions concentrated on sets of complicated structures.

The approximate solutions of Fredholm integral equations on Cantor sets within local fractional operators

In this paper, we apply the local fractional Adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of Fredholm integral equations of the second kind within local fractional derivative operators. The iteration procedure is based on local fractional derivative. The obtained results reveal that the proposed methods are very efficient and simple tools ...

Schrödinger Operators with Δ and Δ′-interactions on Lipschitz Surfaces and Chromatic Numbers of Associated Partitions

We investigate Schrödinger operators with δ and δ′-interactions supported on hypersurfaces, which separate the Euclidean space into finitely many bounded and unbounded Lipschitz domains. It turns out that the combinatorial properties of the partition and the spectral properties of the corresponding operators are related. As the main result we prove an operator inequality for the Schrödinger ope...

Limit-periodic Schrödinger Operators in the Regime of Positive Lyapunov Exponents

We investigate the spectral properties of the discrete one-dimensional Schrödinger operators whose potentials are generated by continuous sampling along the orbits of a minimal translation of a Cantor group. We show that for given Cantor group and minimal translation, there is a dense set of continuous sampling functions such that the spectrum of the associated operators has zero Hausdorff dime...

Schrödinger Operators with Δ-interactions Supported on Conical Surfaces

We investigate the spectral properties of self-adjoint Schrödinger operators with attractive δ-interactions of constant strength α > 0 supported on conical surfaces in R3. It is shown that the essential spectrum is given by [−α2/4,+∞) and that the discrete spectrum is infinite and accumulates to −α2/4. Furthermore, an asymptotic estimate of these eigenvalues is obtained.

Smale Horseshoes and Symbolic Dynamics in Perturbed Nonlinear Schrödinger Equations

In [12], we gave an intensive study on the level sets of the integrable cubic nonlinear Schrödinger (NLS) equation. Based upon that study, the existence of a symmetric pair of homoclinic orbits in certain perturbed NLS systems was established in [11]. [Stated in Theorem 1.3 below.] In this paper, the existence of Smale horseshoes and symbolic dynamics is established in the neighborhood of the s...
