Infinite asymptotic games [PDF]

open access: yes, 2008
We study infinite asymptotic games in Banach spaces with an F.D.D. and prove that analytic games are determined by characterising precisely the conditions for the players to have winning strategies.

Asymptotic resemblance [PDF]

open access: yesRocky Mountain Journal of Mathematics, 2016
Uniformity and proximity are two different ways for defining small scale structures on a set. Coarse structures are large scale counterparts of uniform structures. In this paper, motivated by the definition of proximity, we develop the concept of asymptotic resemblance as a relation between subsets of a set to define a large scale structure on it.

Asymptotic convergence of the solution for singularly perturbed boundary value problem with boundary jumps

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
The article is devoted to study of boundary value problem with boundary jumps for third order linear integro-differential equation with a small parameter at the highest derivatives, provided that additional characteristic equation’s roots have opposite ...

Asymptotics of Eigenvalues of First Boundary Value Problem for Singularly Pertubed Second-order Differential Equation with Turning Points

open access: yesМоделирование и анализ информационных систем, 2015
We consider a linear differential equation of second order with a small factor at the highest derivative. We study the problem of the asymptotic behavior of the eigenvalues of the first boundary value problem (task Dirichlet) in situation when the turning ...

Dynamics of Dollard asymptotic variables. Asymptotic fields in Coulomb scattering [PDF]

open access: yes, 2016
Generalizing Dollard's strategy, we investigate the structure of the scattering theory associated to any large time reference dynamics $U_D(t)$ allowing for the existence of M{\o}ller operators.

Full Waveform Inversion Based on an Asymptotic Solution of Helmholtz Equation

open access: yesGeosciences, 2023
This study considers the full waveform inversion (FWI) method based on the asymptotic solution of the Helmholtz equation. We provide frequency-dependent ray tracing to obtain the wave field used to compute the FWI gradient and calculate the modeled data.

Expectile asymptotics

open access: yesElectronic Journal of Statistics, 2016
We discuss in detail the asymptotic distribution of sample expectiles. First, we show uniform consistency under the assumption of a finite mean. In case of a finite second moment, we show that for expectiles other then the mean, only the additional assumption of continuity of the distribution function at the expectile implies asymptotic normality ...

Minimal model for tidal bore revisited

open access: yesNew Journal of Physics, 2019
This develops a recent analysis of gentle undular tidal bores (2018 New J. Phys. 20 053066) and corrects an error. The simplest linear-wave superposition, of monochromatic waves propagating according to the shallow-water dispersion relation, leads to a ...

Relaxation Oscillations in a System with Delays Modeling the Predator-Prey Problem

open access: yesМоделирование и анализ информационных систем, 2013
A new asymptotic method for investigating complex relaxation oscillations of a system with delay was offered. Applying it, we can reduce the problem of predator-prey system dynamics to problem of one-dimensional maps analysis.

On the Diophantine Equation z(n) = (2 − 1/k)n Involving the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2020
Let ( F n ) n ≥ 0 be the sequence of the Fibonacci numbers. The order (or rank) of appearance z ( n ) of a positive integer n is defined as the smallest positive integer m such that n divides F m .
