Unitary boundary pairs for isometric operators in Pontryagin spaces and generalized coresolvents
D. Baidiuk, V. Derkach, S. Hassi
An isometric operator V in a Pontryagin space H is called standard, if its domain and the range are nondegenerate subspaces in H. A description of coresolvents for standard isometr…
On a class of integral systems
Volodymyr Derkach, Dmytro Strelnikov, Henrik Winkler
We study spectral problems for two--dimensional integral system with two given non-decreasing functions , on an interval which is a generalization of the Krein s…
Some properties of generalized hypergeometric Appell polynomials
L Bedratyuk., N. Luno
In this paper, we present a new real-valued Appell-type polynomial family every member of which is expressed by mean of a generalized hypergeometric function. Th…
Wiener algebras and trigonometric series in a coordinated fashion
E. Liflyand, R. Trigub
Let be the Wiener Banach algebra of functions representable by the Fourier integrals of Lebesgue integrable functions. It is proven in the paper that, in particula…
Spin wave modes in a cylindrical nanowire in crossover dipolar-exchange regime
J. Rychły, V. S. Tkachenko, J. W. Kłos +2
Nanoscale magnetic systems have been studied extensively in various geometries, such as wires of different cross-sections, arrays of wires, dots, rings, etc. Such systems have inte…
Completeness property of one-dimensional perturbations of normal and spectral operators generated by first order systems
Anton A. Lunyov, Mark M. Malamud
The paper is concerned with completeness property of rank one perturbations of unperturbed operators generated by special boundary value problems (BVP) for the following $2 \times…
