Global existence and exponential growth for a viscoelastic wave equation with dynamic boundary conditions

Advances in Nonlinear Analysis, 2013
The goal of this work is to study a model of the wave equation with dynamic boundary conditions and a viscoelastic term. First, applying the Faedo–Galerkin method combined with the fixed point theorem, we show the existence and uniqueness of a local in ...

Exponential Growth of Solutions for Nonlinear Coupled Viscoelastic Wave Equations

Universal Journal of Mathematics and Applications, 2019
In this work, we consider an initial-boundary value problem related to the nonlinear coupled viscoelastic equations \[ \left\{ \begin{array}{c} \left\vert u_{t}\right\vert ^{j}u_{tt}-\Delta u_{tt}-div\left( \left\vert \nabla u\right\vert ^{\alpha -2 ...

Growth of quotients of groups acting by isometries on Gromov hyperbolic spaces [PDF]

, 2012
We show that every non-elementary group $G$ acting properly and cocompactly by isometries on a proper geodesic Gromov hyperbolic space $X$ is growth tight. In other words, the exponential growth rate of $G$ for the geometric (pseudo)-distance induced by $

Exponential energy growth in adiabatically changing Hamiltonian Systems [PDF]

, 2014
Fermi acceleration is the process of energy transfer from massive objects in slow motion to light objects that move fast. The model for such process is a time-dependent Hamiltonian system.

Control and maintenance of mammalian cell size

BMC Cell Biology, 2004
Background Conlon and Raff propose that mammalian cells grow linearly during the division cycle. According to Conlon and Raff, cells growing linearly do not need a size checkpoint to maintain a constant distribution of cell sizes.

On exponential growth and uniformly exponential growth for groups

Inventiones Mathematicae, 2004
The paper gives a negative answer to \textit{M. Gromov}'s question [Structures métriques pour les variétés riemanniennes. Textes Mathématiques, 1. Paris (1981; Zbl 0509.53034)], (Remark 5.2) posed in 1981. Gromov asked `if groups of exponential growth necessarily have uniform exponential growth'.
