Slow solitary waves in multi-layered magnetic structures [PDF]

open access: yes, 2001
The propagation of slow sausage surface waves in a multi-layered magnetic configuration is considered. The magnetic configuration consists of a central magnetic slab sandwiched between two identical magnetic slabs (with equilibrium quantities different ...

To the solution of one pseudo-Volterra integral equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2019
In this paper, we study a homogeneous singular integral Volterra equation of the second kind (pseudoVolterra integral equation). The singularity of the integral equation is shown. Properties of its kernel are proved.

The Characteristic Equation

open access: yes, 2023
AbstractThis chapter is devoted to compact graphs formed by a finite number of bounded intervals. We already know that the spectrum of the corresponding magnetic Schrödinger operator is discrete and our main goal is to obtain characteristic equations determining the spectrum (eigenvalues) precisely. We describe here three different methods to obtain an

Maxwell’s Mixing Equation Revisited: Characteristic Impedance Equations for Ellipsoidal Cells [PDF]

open access: yesBiophysical Journal, 2015
We derived a series of, to our knowledge, new analytic expressions for the characteristic features of the impedance spectra of suspensions of homogeneous and single-shell spherical, spheroidal, and ellipsoidal objects, e.g., biological cells of the general ellipsoidal shape.

Characteristic Surface Data for the Eikonal Equation

open access: yes, 1998
A method of solving the eikonal equation, in either flat or curved space-times, with arbitrary Cauchy data, is extended to the case of data given on a characteristic surface. We find a beautiful relationship between the Cauchy and characteristic data for

Relative Free Energy Function and Structural Theory of Thermoeconomics

open access: yesEnergies, 2020
This paper explores the advantages of using relative free energy instead of exergy to build a mathematical theory of thermodynamic costs to diagnose malfunctions in thermal systems.

Formation of Small-Scale Condensations in the Molecular Clouds via Thermal Instability

open access: yes, 2006
A systematic study of the linear thermal instability of a self-gravitating magnetic molecular cloud is carried out for the case when the unperturbed background is subject to local expansion or contraction.

Light Beams Distortion in Nonlinear Electrodynamics [PDF]

open access: yes, 1998
We obtain the characteristic equation for the nonlinear Born-Infeld electrodynamics. This equation has the form of the characteristic equation for the linear electrodynamics in some effective Riemann space.

On the stability and Hopf bifurcation of the non-zero uniform endemic equilibrium of a time-delayed malaria model

open access: yesNonlinear Analysis, 2016
This article considers a time-delayed mathematical model of immune response to Plasmodium falciparum (Pf) malaria. Infected red blood cells display a wide variety of surface antigens to which the body in turn responds by mounting specific immune ...

The method of simple iterations with correction of convergence and the minimal discrepancy method for plasmonic problems

open access: yesФизика волновых процессов и радиотехнические системы, 2021
The problem of searching for complex roots of the dispersion equations of plasmon-polaritons along the boundaries of the layered structure-vacuum interface is considered. Such problems arise when determining proper waves along the interface of structures
