General decay rate of a weakly dissipative viscoelastic equation with a general damping [PDF]

Opuscula Mathematica, 2020
In this paper, we consider a weakly dissipative viscoelastic equation with a nonlinear damping. A general decay rate is proved for a wide class of relaxation functions. To support our theoretical findings, some numerical results are provided.

Numerical and Theoretical Stability Study of a Viscoelastic Plate Equation with Nonlinear Frictional Damping Term and a Logarithmic Source Term

Mathematical and Computational Applications, 2022
This paper is designed to explore the asymptotic behaviour of a two dimensional visco-elastic plate equation with a logarithmic nonlinearity under the influence of nonlinear frictional damping. Assuming that relaxation function g satisfies g′(t)≤−ξ(t)G(g(

General Decay of the Moore–Gibson–Thompson Equation with Viscoelastic Memory of Type II

Journal of Function Spaces, 2022
This study deals with the general decay of solutions of a new class of Moore–Gibson–Thompson equation with respect to the memory kernel of type II. By using the energy method in the Fourier space, we establish the main results.

Asymptotic stability of a viscoelastic problem with time-varying delay in boundary feedback [PDF]

Theoretical and Applied Mechanics, 2021
In this paper, we investigate a nonlinear viscoelastic equation. By assuming time-varying delay feedback acting on the boundary, under certain assumptions on the given data, the general decay estimates for the energy are established by introducing ...

Global existence, general decay and blow-up for a nonlinear wave equation with logarithmic source term and fractional boundary dissipation

Discrete and Continuous Dynamical Systems. Series A, 2022
In this paper, we consider a wave equation with logarithmic source term and fractional boundary dissipation. We study the global existence of the solution under some conditions and prove the general decay of the solution in this case by using the ...

DECAYS OF FOURTH GENERATION BOUND STATES [PDF]

International Journal of Modern Physics A, 2012
We consider the decay modes of the heavy [Formula: see text] bound states originating from Higgs boson exchange between quark–antiquark pair. In case of a small coupling between the fourth and lower generation the main decay mode is [Formula: see text] annihilation.

HADRONIC B DECAYS: A GENERAL APPROACH [PDF]

International Journal of Modern Physics A, 2007
In this paper, we propose a general approach for describing hadronic B decays. Using this method, all amplitudes for such decays can be expressed in terms of contractions, though the matrix elements are not evaluated. Many years ago, Buras and Silvestrini proposed a similar approach. However, our technique goes beyond theirs in several ways. First, we

Stability result for Lord Shulman swelling porous thermo-elastic soils with distributed delay term

Open Mathematics, 2023
The Lord Shulman swelling porous thermo-elastic soil system with the presence of a distributed delay term is studied in this work. We will establish the well-posedness of the system and the exponential stability of the system is derived.

Partial stability analysis of stochastic differential equations with a general decay rate

Journal of Engineering Mathematics, 2021
This paper is concerned with the almost sure partial practical stability of stochastic differential equations with general decay rate. We establish some sufficient conditions based upon the construction of appropriate Lyapunov functions.
