Asymptotic proximity to higher order nonlinear differential equations

Advances in Nonlinear Analysis, 2022
The existence of unbounded solutions and their asymptotic behavior is studied for higher order differential equations considered as perturbations of certain linear differential equations.

Correlations for pairs of periodic trajectories for open billiards

, 2009
In this paper we prove two asymptotic estimates for pairs of closed trajectories for open billiards similar to those established by Pollicott and Sharp for closed geodesics on negatively curved compact surfaces.

Scalar boundary value problems on junctions of thin rods and plates. I. Asymptotic analysis and error estimates

, 2014
We derive asymptotic formulas for the solutions of the mixed boundary value problem for the Poisson equation on the union of a thin cylindrical plate and several thin cylindrical rods.

Asymptotics for Configural Location Estimators

The Annals of Statistics, 1986
Let \(x_ 1,...,x_ n\) be independent real-valued observations from the distribution function (d.f.) F(x-\(\mu)\); it is assumed that F(\(\cdot)\) is symmetric around 0 ...

M-test in linear models with negatively superadditive dependent errors

Journal of Inequalities and Applications, 2017
This paper is concerned with the testing hypotheses of regression parameters in linear models in which errors are negatively superadditive dependent (NSD). A robust M-test base on M-criterion is proposed. The asymptotic distribution of the test statistic

Imaging polarizable dipoles

, 2017
We present a method for imaging the polarization vector of an electric dipole distribution in a homogeneous medium from measurements of the electric field made at a passive array. We study an electromagnetic version of Kirchhoff imaging and prove, in the
