On the boundary-value problem for a mixed-type equation: Asymptotic analysis and an effective numerical algorithm
Autor: T. O. Kapustina
Publikováno v: Moscow University Computational Mathematics and Cybernetics. 41:157-164
A singularly perturbed boundary-value problem for an equation of mixed ellipticparabolic type is considered. The first part of this work is devoted to an asymptotic study of the solution to the problem. Modification of the boundary function method fo

New criterion for asymptotic stability of time-varying dynamical systems
Autor: Mohamed Hammami, Mekki Hammi, Mohamed Mabrouk, Taoufik Ghrissi
Publikováno v: Kybernetika. :331-353
In this paper, we establish some new sufficient conditions for uniform global asymptotic stability for certain classes of nonlinear systems. Lyapunov approach is applied to study exponential stability and stabilization of time-varying systems. Suffic

The asymptotic solution of the three-band bisingularly problem
Autor: D. A. Tursunov
Publikováno v: Lobachevskii Journal of Mathematics. 38:542-546
The paper proposes an analogue of Vishik–Lyusternik–Vasileva–Imanalieva boundary functions method for constructing a uniform asymptotic expansion of solutions to many band (or with an intermediate boundary layers) bisingularly problems. By mean

Asymptotic calculation of the heat distribution in a plane
Autor: S. V. Zakharov
Publikováno v: Proceedings of the Steklov Institute of Mathematics. 296:243-249
For the heat equation in the plane, an asymptotic approximation of the solution of the Cauchy problem for large times is constructed in the case where the initial function has a power-like asymptotics at infinity. In addition to direct application to

On t-dependent hyperbolic systems. Part 2
Autor: Jens Wirth
Publikováno v: Journal of Mathematical Analysis and Applications. 448:293-318
We consider hyperbolic equations with time-dependent coefficients and develop an abstract framework to derive the asymptotic behaviour of the representation of solutions for large times. We are dealing with generic situations where the large-time asy

Asymptotic support of localized solutions of the linearized system of magnetohydrodynamics
Autor: A. I. Allilueva, Andrei I. Shafarevich
Publikováno v: Russian Journal of Mathematical Physics. 23:425-430
The asymptotic behavior of solutions of the Cauchy problem for the linearized system of magnetohydrodynamic equations with initial conditions localized near a two-dimensional surface was obtained by the authors earlier. Here, this asymptotic behavior
