Polynomial Decay Rate for Kirchhoff Type in Viscoelasticity with Logarithmic Nonlinearity and Not Necessarily Decreasing Kernel

Symmetry, 2019
This paper describes a polynomial decay rate of the solution of the Kirchhoff type in viscoelasticity with logarithmic nonlinearity, where an asymptotically-stable result of the global solution is obtained taking into account that the kernel is not ...

Optimal polynomial decay of functions and operator semigroups [PDF]

Mathematische Annalen, 2010
International audienceWe characterize the polynomial decay of orbits of Hilbert space C 0-semigroups in resolvent terms. We also show that results of the same type for general Banach space semigroups and functions obtained recently in Batty and ...

Polynomial Fourier decay for fractal measures and their pushforwards

Mathematische Annalen
We prove that the pushforwards of a very general class of fractal measures μ on Rd under a large family of non-linear maps F : Rd → R exhibit polynomial Fourier decay: there exist C, η > 0 such that |cFμ(ξ)| ≤ C|ξ|−η for all ξ ̸= 0.

Exponential and Polynomial Decay Rates of a Porous Elastic System with Thermal Damping

Journal of Function Spaces, 2023
This paper concerns a linear porous thermoelastic system, where the heat conduction is given by Cattaneo’s law. By using the theory of the semigroup of the linear operator, the well-posedness is proven.

Polynomial decay of correlations for almost Anosov diffeomorphisms

Ergodic Theory and Dynamical Systems, 2017
We investigate the polynomial lower and upper bounds for decay of correlations of a class of two-dimensional almost Anosov diffeomorphisms with respect to their Sinai–Ruelle–Bowen (SRB) measures.

Polynomial Decay of the Energy of Solutions of the Timoshenko System with Two Boundary Fractional Dissipations

Fractal and Fractional
In this study, we examine Timoshenko systems with boundary conditions featuring two types of fractional dissipations. By applying semigroup theory, we demonstrate the existence and uniqueness of solutions.

Energy Decay Estimates of a Timoshenko System with Two Nonlinear Variable Exponent Damping Terms

Mathematics, 2023
This paper is concerned with the asymptotic behavior of the solution of a Timoshenko system with two nonlinear variable exponent damping terms. We prove that the system is stable under some specific conditions on the variable exponent and the equal wave ...
