Perturbation of the Hill operator by narrow potentials

Russian Mathematics, 2017
The operator, considered in the paper, is a special case of the Hill operator, a perturbation of a periodic second order differential operator, defined on the real axis, which describes the one-dimensional model of the Bloch electron in a crystal placed in an external electric field.

Atomic Operators in the Theory of Narrow‐Band Magnetic Semiconductors

physica status solidi (b), 1984
AbstractAn exact equivalence of s—dexchange model and the degenerate Hubbard model is shown using the atomic operator representation. The analogy of exact Nagaoka's theorem is proved for a narrowband semiconductor with one carrier and infinite exchange interaction. Using the diagram technique for the Hubbard operators the energy of acoustic and optical

(Strongly-)Dunford–Pettis Operators and Narrow Operators

Integral Equations and Operator Theory, 2023
The paper is devoted to investigation of ``small'' operators on symmetric spaces over von Neumann algebras and Köthe-Bochner spaces over finite measure spaces. Let ``operator'' mean linear bounded operator. Theorem~3.8 asserts that, under mild assumptions on a symmetric space \(E\) on \([0,1]\) and a semifinite von Neumann algebra \(\mathcal{M}\), an ...
