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 Estimates and Smoothness of the Moduli Space of Pseudoholomorphic Curves [PDF]
Memoirs of the American Mathematical Society, 2016 The compacified moduli space of bordered stable maps carries a Kuranishi structure with boundary. Smoothness of Kuranishi structure along the boundary requires smoothness of coordinate changes along the boundary. The proof of smoothness is written by the

On the decay of exponential type for the solutions in a dipolar elastic body
Journal of Taibah University for Science, 2020 Our study is concerned with a generalization of the principle of Saint-Venant in the context of the theory of elastic bodies with a dipolar structure.

Positive Hamiltonians can give purely exponential decay [PDF]
, 2017 It is commonly claimed that only Hamiltonians with a spectrum unbounded both above and below can give purely exponential decay. Because such Hamiltonians have no ground state, they are considered unphysical.

Exponential decay of scattering coefficients [PDF]
International Conference on Sampling Theory and Applications, 2016 The scattering transform is a deep representation, defined as a cascade of wavelet transforms followed by the application of a complex modulus. In her PhD, the author showed that, under some conditions on the wavelets, the norm of the scattering ...

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.

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 ...

Exponential decay of dispersion managed solitons for vanishing average dispersion [PDF]
, 2010 We show that any $L^2$ solution of the Gabitov-Turitsyn equation describing dispersion managed solitons decay exponentially in space and frequency domains. This confirms in the affirmative Lushnikov's conjecture of exponential decay of dispersion managed
