Sharp polynomial bounds on decay of correlations for multidimensional nonuniformly hyperbolic systems and billiards [PDF]

, 2021
Gouëzel and Sarig introduced operator renewal theory as a method to prove sharp results on polynomial decay of correlations for certain classes of nonuniformly expanding maps.

Optimal Decay Rates for Kirchhoff Plates with Intermediate Damping

Trends in Computational and Applied Mathematics, 2020
In this paper we study the asymptotic behavior of Kirchhoff plates with intermediate damping. The damping considered contemplates the frictional and the Kelvin-Voigt type dampings. We show that the semigroup those equations decays polynomially in time at

Global existence and polynomial decay for a problem with Balakrishnan-Taylor damping [PDF]

, 2008
summary:A viscoelastic Kirchhoff equation with Balakrishnan-Taylor damping is considered. Using integral inequalities and multiplier techniques we establish polynomial decay estimates for the energy of the problem.

Non-cutoff Boltzmann equation with polynomial decay perturbations

Revista Matemática Iberoamericana, 2020
The Boltzmann equation without the angular cutoff is considered when the initial data is a small perturbation of a global Maxwellian and decays algebraically in the velocity variable. We obtain a well-posedness theory in the perturbative framework for both mild and strong angular singularities.

Decay of Geometry for a Class of Cubic Polynomials

Communications in Mathematics and Statistics
In this paper we study a class of bimodal cubic polynomials for which its critical points have the same $ω$-limit set which is an invariant Cantor set. These maps have generalized Fibonacci combinatorics in terms of generalized renormalization on the twin principal nest.

General stability for the Kirchhoff-type equation with memory boundary and acoustic boundary conditions

Boundary Value Problems, 2017
In this paper we consider the existence and general energy decay rate of global solution to the mixed problem for the Kirchhoff-type equation with memory boundary and acoustic boundary conditions.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
