We give coarse geometric conditions for a metric space X to have N-connected asymptotic cones. These conditions are expressed in terms of certain filling functions which are defined recursively on dim...
Asymptotic and bifurcation analysis of wave-pinning in a reaction-diffusion model for cell polarization
wave-pinning bistable reaction-diffusion system mass conservation
2010/12/28
We describe and analyze a bistable reaction-diffusion (RD) model for two interconverting chemical species that exhibits a phenomenon of wave-pinning: a wave of activation of one of the species is init...

Let G be a reductive algebraic group over C and denote its Lie algebra by g. Let Oh be a closed G-orbit through a semisimple element h ∈ g. By a result of Borho and Kraft [BK79], it is known that the ...
Asymptotic estimates on the time derivative of entropy on a Riemannian manifold
the time derivative entropy Riemannian manifold
2010/11/23
We consider the entropy of the solution to the heat equation on a Riemannian manifold. When the manifold is compact, we provide two estimates on the rate of change of the entropy in terms of the lower...

Consider a quantum system S that interacts sequentially with a chain (environment) of identical
probes C = P + P + : : :, with each interaction governed by a xed interaction time and operator V .I...

Asymptotic of geometrical navigation random set of points plane
2010/12/10
A navigation on a set of points is a rule for choosing which point to move to from the
present point in order to progress toward a specified target. In the present paper we study
some “geometrical b...
Asymptotic growth of saturated powers and epsilon multiplicity
Asymptotic growth of saturated powers epsilon multiplicity
2010/12/9
In this paper, we study the growth of saturated powers of modules. In the case of an ideal I in a local ring (R,m), the saturation of Ik in R is (Ik)sat = Ik :R m ∞ = ∪∞n=1Ik :R m n.
Finite-SNR Diversity-Multiplexing Tradeoff via Asymptotic Analysis of Large MIMO Systems
Diversity-multiplexing tradeoff outage probability
2010/12/9
Diversity–multiplexing tradeoff (DMT) was characterized asymptotically (SNR-> infinity) for i.i.d. Rayleigh fading channel by Zheng and Tse [1].
Asymptotic stability of solutions to abstract differential equations
Nonlinear inequality Asymptotic stability Abstract differential equations
2010/12/15
An evolution problem for abstract differential equations is studied. The typical problem is:
˙ u = A(t)u+F(t,u), t ≥ 0; u(0) = u0; ˙ u =du dt ∗)Here A(t) is a linear bounded operator in a Hilbe...
Asymptotic Analysis to a Phase-Field Model with a Nonsmooth Memory Kernel
Asymptotic Analysis Phase-Field Model Nonsmooth Memory Kernel
2009/1/20
A phase-field model based on the Gurtin-Pipkin heat flux law is considered. The resulting system has been investigated by Colli and Laurencot who proved existence and uniqueness results, when the time...
Asymptotic Approximationof Jacobi Functions and Their Zeros with Error Bounds
Asymptotic approximation Jacobi function Zero Error bounds
2007/12/12
The study of zeros of orthogonal functions is an important topic. In this paper, by improving the middle variable $x(t)$, we've got a new form of asymptotic approximation, completed with error bounds,...
A Remark on the Asymptotic Properties of Positive Homogeneous Maps on Homogeneous Lattices
Lyapunov Exponents asymptotic stability
2010/3/1
An abstract version of Lyapunov exponents is defined for positive homogeneous maps on Homogeneous Lattices and a sufficient condition is given for the asymptotic stability of the map.
