Dark-Halo Cusp: Asymptotic Convergence [PDF]

open access: yesThe Astrophysical Journal, 2002
We propose a model for how the buildup of dark halos by merging satellites produces a characteristic inner cusp, of a density profile \rho \prop r^-a with a -> a_as > 1, as seen in cosmological N-body simulations of hierarchical clustering scenarios ...

REGRESSION ASYMPTOTICS USING MARTINGALE CONVERGENCE METHODS [PDF]

open access: yesEconometric Theory, 2008
Weak convergence of partial sums and multilinear forms in independent random variables and linear processes and their nonlinear analogues to stochastic integrals now plays a major role in nonstationary time series and has been central to the development of unit root econometrics.

Convergence of asymptotic directions [PDF]

open access: yesTransactions of the American Mathematical Society, 2001
In this interesting paper the authors study convergence properties of asymptotic cones in relation with continuity properties of set-valued maps. Beside the usual lower, upper and upper Hausdorff continuity, closedness and boundedly compactness for set-valued maps, they use adequate notions for cone-valued maps like cosmic upper and lower continuity ...

Asymptotic convergence of evolving hypersurfaces [PDF]

open access: yesRevista Matemática Iberoamericana, 2021
If \psi\colon M^n\to \mathbb{R}^{n+1} is a smooth immersed closed hypersurface, we consider the functional \mathcal{F}_m(\psi) = \int_M 1 + |\nabla^m \nu |^2 \, d\mu,

Curious convergence properties of lattice Boltzmann schemes for diffusion with acoustic scaling [PDF]

open access: yes, 2018
We consider the D1Q3 lattice Boltzmann scheme with an acoustic scale for the simulation of diffusive processes. When the mesh is refined while holding the diffusivity constant, we first obtain asymptotic convergence.

A sharp analysis on the asymptotic behavior of the Durbin-Watson statistic for the first-order autoregressive process [PDF]

open access: yes, 2011
The purpose of this paper is to provide a sharp analysis on the asymptotic behavior of the Durbin-Watson statistic. We focus our attention on the first-order autoregressive process where the driven noise is also given by a first-order autoregressive ...

Asymptotic extraction approach for antennas in a multilayered spherical media [PDF]

open access: yes, 2010
An efficient algorithm is introduced to enhance the convergence of dyadic Green's functions (DGF) in a layered spherical media where asymptotic expressions have been developed. The formulated expressions involve an infinite series of spherical eigenmodes

Analysis and Design of Tuned Turbo Codes [PDF]

open access: yes, 2012
It has been widely observed that there exists a fundamental trade-off between the minimum (Hamming) distance properties and the iterative decoding convergence behavior of turbo-like codes.

Global Asymptotic Convergent Observer for SLAM

open access: yesIEEE Access, 2022
This paper examines the global convergence problem of SLAM algorithms, an issue that faces topological obstructions. This is because the state-space of attitude dynamics is defined on a non-contractible manifold: the special orthogonal group of order three SO(3).

Convergence Characteristics of the Cumulant Expansion for Fourier Path Integrals [PDF]

open access: yes, 2010
The cumulant representation of the Fourier path integral method is examined to determine the asymptotic convergence characteristics of the imaginary-time density matrix with respect to the number of path variables $N$ included. It is proved that when the
