The problem of acceleration in the dynamics of a double-link wheeled vehicle with arbitrarily directed periodic excitation [PDF]

Theoretical and Applied Mechanics, 2023
This study investigates the motion of a nonholonomic mechanical system that consists of two wheeled carriages articulated by a rigid frame. There is a point mass which oscillates at a given angle 𝛼 to the main axis of one of the carriages.

Dynamics of full-coupled chains of a great number of oscillators with a large delay in couplings [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика, 2023
The subject of this work is the study of local dynamics of full-coupled chains of a great number of oscillators with a large delay in couplings. From a discrete model describing the dynamics of a great number of coupled oscillators, a transition has been

Uniform Approximation to the Solution of a Singularly Perturbed Boundary Value Problem with an Initial Jump

Mathematics, 2020
In this study, a third-order linear integro-differential equation with a small parameter at two higher derivatives was considered. An asymptotic expansion of the solution to the boundary value problem for the considered equation is constructed by ...

Asymptotic Stability of Solutions to a Nonlinear Urysohn Quadratic Integral Equation [PDF]

International Journal of Analysis, 2013
Here, we prove the existence of -nondecreasing solution to a nonlinear quadratic integral equation of Urysohn type by applying the technique of weak noncompactness. Also, the asymptotic stability of solutions for that quadratic integral equation is studied.

Asymptotic growth of the 4d N $$ \mathcal{N} $$ = 4 index and partially deconfined phases

Journal of High Energy Physics, 2020
We study the Cardy-like asymptotics of the 4d N $$ \mathcal{N} $$ = 4 index and demonstrate the existence of partially deconfined phases where the asymptotic growth of the index is not as rapid as in the fully deconfined case.

Asymptotic Behavior of Solutions to a Vector Integral Equation with Deviating Arguments [PDF]

Abstract and Applied Analysis, 2013
In this paper, we propose the study of an integral equation, with deviating arguments, of the typey(t)=ω(t)-∫0∞‍f(t,s,y(γ1(s)),…,y(γN(s)))ds,t≥0,in the context of Banach spaces, with the intention of giving sufficient conditions that ensure the existence of solutions with the same asymptotic behavior at∞asω(t).

Dirichlet problem for mixed type equation with characteristic degeneration

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
For a mixed elliptic-hyperbolic type equation with characteristic degeneration, the first boundary value problem in a rectangular region is investigated. The criterion for the uniqueness of the solution of the problem is established.

Asymptotics of the Solutions to Singularly Perturbed Multidimensional Integral Equations

Journal of Mathematical Analysis and Applications, 1995
The object of the study in the paper is the singularly perturbed integral equation of the form \[ \varepsilon h_ \varepsilon(x)+ \int_ T R(x- y) h_ \varepsilon(y) dy= f(x),\tag{1} \] \(x\in T\), where \(\varepsilon> 0\) is a parameter, \(T\) is a bounded domain in \(\mathbb{R}^ n\) with a smooth boundary and \(f(x)\) is a given smooth function ...
