Qualitative analysis of strictly non-Volterra quadratic dynamical systems with continuous time
Rasulov Xaydar Raupovich
In this article, a continuous analogue of strictly non-Volterra quadratic dynamical systems with continuous time and points of equilibrium is investigated, a phase portrait of the…
Optimal quadrature formulas for computing of Fourier integrals in a Hilbert space
A. R. Hayotov, S. S. Babaev
In the present paper the optimal quadrature formulas in the sense of Sard are constructed for numerical integration of the integral with $ω\in \mathbb{R…
Optimal interpolation formulas in space
S. S. Babaev, A. R. Hayotov
In the present paper optimal interpolation formulas are constructed in space. Explicit formulas for coefficients of optimal interpolation formulas are obtained…
On the spectrum of the lattice spin-boson Hamiltonian for any coupling: 1D case
Mukhiddin Muminov, Hagen Neidhardt, Tulkin Rasulov
A lattice model of radiative decay (so-called spin-boson model) of a two level atom and at most two photons is considered. The location of the essential spectrum is described. For…
