Third-order inverse spectral problem with the three-point boundary conditions
Natalia P. Bondarenko
In this paper, we study a new inverse spectral problem that consists in the recovery of the third-order differential equation from two spectra corresponding to the boundary conditi…
Classification of coadjoint orbits for the maximal unipotent subgroup in the simple group of type F_4
Matvey A. Surkov
Let N be the maximal unipotent subgroup in the simple algebraic group of type Φ. It naturally acts on the space dual to the Lie algebra n of N, and this action is called coadjoint.…
On the analog of the Kolmogorov-Arnold superposition representation for continuous functions of several -adic variables
Alexander P. Zubarev
It is shown that any continuous function depending on several -adic variables, each of which is defined on , can be represented as a superposition of continuous…
Uniform stability for the inverse Sturm-Liouville problem with eigenparameter-dependent boundary conditions
Natalia P. Bondarenko
We consider a class of self-adjoint Sturm-Liouville problems with rational functions of the spectral parameter in the boundary conditions. The uniform stability for direct and inve…
Production of -wave charmonia in the soft gluon resummation approach using the NRQCD
Vladimir Saleev, Kirill Shilyaev
In this article, we study the wave charmonium production at the small transverse momenta in the transverse momentum dependent (TMD) parton model (PM), as it is formulated in th…
Generation of Deep Ultraviolet Optical Vortices via Amplitude and Phase Spiral Zone Plates
A. S. Dyatlov, M. A. Nozdrin, A. N. Sergeev +3
We present the development and experimental implementation of diffractive optical elements designed to generate optical vortices in the deep ultraviolet range (from 260 to 266 nm).…
