Asymptotic behavior of nonlinear diffusions [PDF]

open access: yesMathematical Research Letters, 2003
We describe the asymptotic behavior as t → ∞ of the solution of ut = ∆pu in IRN, for (2N +1)/(N +1) ≤ p < N and non-negative, integrable initial data. Optimal rates in Lq , q = 2 − 1/(p − 1) for the convergence towards a self-similar profile corresponding to a solution with Dirac distribution initial data are found.

Classification of Asymptotic Behavior in a Stochastic SIR Model [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2015
This paper investigates asymptotic behavior of a stochastic SIR epidemic model, which is a system with degenerate diffusion. It gives sufficient conditions that are very close to the necessary conditions for the permanence.

The Asymptotic Behavior of Grassmannian Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2012
The iterated Johnson bound is the best known upper bound on a size of an error-correcting code in the Grassmannian $\mathcal{G}_q(n,k)$. The iterated Sch nheim bound is the best known lower bound on the size of a covering code in $\mathcal{G}_q(n,k)$. We use probabilistic methods to prove that both bounds are asymptotically attained for fixed $k$ and ...

Asymptotic Regularity and Existence of Time-Dependent Attractors for Second-Order Undamped Evolution Equations with Memory

open access: yesMathematics, 2022
Our purpose in this article is to study the asymptotic behavior of undamped evolution equations with fading memory on time-dependent spaces. By means of the theory of processes on time-dependent spaces, asymptotic a priori estimate and the technique of ...

On the Connection Problem for Painlevé Differential Equation in View of Geometric Function Theory

open access: yesMathematics, 2020
Asymptotic analysis is a branch of mathematical analysis that describes the limiting behavior of the function. This behavior appears when we study the solution of differential equations analytically.

Asymptotic behavior of random Navier-Stokes equations driven by Wong-Zakai approximations

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2019
In this paper, we investigate the asymptotic behavior of the solutions of the two-dimensional stochastic Navier-Stokes equations via the stationary Wong-Zakai approximations given by the Wiener shift.

Asymptotic behavior of Aldous' gossip process [PDF]

open access: yes, 2010
Aldous [(2007) Preprint] defined a gossip process in which space is a discrete $N\times N$ torus, and the state of the process at time $t$ is the set of individuals who know the information.

The asymptotic behavior of a family of sequences [PDF]

open access: yesPacific Journal of Mathematics, 1987
A class of sequences defined by nonlinear recurrences involving the greatest integer function \([.]\) is studied, a typical member of the class being \(a(0)=1\), \(a(n)=a([n/2])+a([n/3])+a([n/6])\) for \(n\geq 1\). For this sequence, it is shown that \(\lim a(n)/n\) as \(n\to \infty\) exists and equals \(12/(log 432)\). More generally, for any sequence

On the representation of m as ∑k=−nnϵkk

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Let A(n,m) be the number of solutions of ∑k=−nnϵkk=m where each ϵk∈{0,1}. We determine the asymptotic behavior of A(n,m) for m=o(n3/2), extending results of van Lint and of Entringer.

Asymptotic behavior of N-fields Chiral cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We perform a detailed analysis for the asymptotic behaviour for the multi-scalar field Chiral cosmological scenario. We present the asymptotic behaviour for the one-field, two-fields and three-fields Chiral models.
