Exponential decay of expansive constants [PDF]
Science China Mathematics, 2013 A map $f$ on a compact metric space is expansive if and only if $f^n$ is expansive. We study the exponential rate of decay of the expansive constant of $f^n$. A major result is that this rate times box dimension bounds topological entropy.

Exponential Decay for Nonlinear von Kármán Equations with Memory
Abstract and Applied Analysis, 2013 We consider the nonlinear von Kármán equations with memory term. We show the exponential decay result of solutions. Our result is established without imposing the usual relation between g and its derivative.

On the exponential decay of magnetic stark resonances [PDF]
Reports on Mathematical Physics, 2005 We study the time decay of magnetic Stark resonant states. As our main result we prove that for sufficiently large time these states decay exponentially with the rate given by the imaginary parts of eigenvalues of certain non-selfadjoint operator. The proof is based on the method of complex translations.

Enhanced observability of quantum post-exponential decay using distant detectors [PDF]
, 2009 We study the elusive transition from exponential to post-exponential (algebraic) decay of the probability density of a quantum particle emitted by an exponentially decaying source, in one dimension. The main finding is that the probability density at the

Constrains on parameters of magnetic field decay for accreting isolated neutron stars [PDF]
, 2000 The influence of exponential magnetic field decay (MFD) on the spin evolution of isolated neutron stars is studied. The ROSAT observations of several X-ray sources, which can be accreting old isolated neutron stars, are used to constrain the exponential ...

Brownian motion in a truncated Weyl chamber [PDF]
, 2010 We examine the non-exit probability of a multidimensional Brownian motion from a growing truncated Weyl chamber. Different regimes are identified according to the growth speed, ranging from polynomial decay over stretched-exponential to exponential decay.

The nature of the long time decay at a second order transition point
, 2001 We show that at a second order phase transition, of \phi^4 like system, a necessary condition for streched exponential decay of the time structure factor is obeyed.

New Journal of Physics, 2022 We identify and investigate the origin and nature of the transition between Gaussian and exponential forms of decoherence: the decoherence factor (that controls the time dependence of the off-diagonal terms of the density matrix expressed in the pointer ...
