DOUBLE WIJSMAN ASYMPTOTIC I2-INVARIANT EQUIVALENCE

open access: yes, 2022
In this study, for double set sequences, we present the notions of Wijsman asymptotic invariant equivalence, Wijsman asymptotic I-2-invariant equiv alence, and Wijsman asymptotic I-2*-invariant equivalence.

Asymptotic coarse Lipschitz equivalence

open access: yes, 2023
We introduce the notion of asymptotic coarse Lipschitz equivalence of metric spaces. We show that it is strictly weaker than coarse Lipschitz equivalence. We study its impact on the asymptotic dimension of metric spaces.

Affine-periodic solutions by asymptotic and homotopy equivalence

open access: yesBoundary Value Problems, 2020
This paper studies the existence of affine-periodic solutions which have the form of x ( t + T ) = Q x ( t ) $x(t+T)=Qx(t)$ with some nonsingular matrix Q.

The Ψ–Asymptotic Equivalence of the Lyapunov Matrix Differential Equations with Integral Term as Right Side and Modified Argument

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2022
Using the notion of strict h-contraction, existence results for Ψ-asymptotic equivalence of two pairs of (Lyapunov) matrix differential equations with integral term as right side and modified argument are given.

Asymptotic unitary equivalence in C*-algebras [PDF]

open access: yesRussian Journal of Mathematical Physics, 2015
Let $C=C(X)$ be the unital $C^*$-algebra of all continuous functions on a finite CW complex $X$ and let $A$ be a unital simple $C^*$-algebra with tracial rank at most one. We show that two unital monomorphisms $ϕ, ψ: C\to A$ are asymptotically unitarily equivalent, i.e., there exists a continuous path of unitaries $\{u_t: t\in [0,1)\}\subset A$ such ...

Asymptotic equivalence and summability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
This paper is a study of the relatioship. between the asymptotic equivalence of two sequences (limnxn/yn=1) and three variatious of this equivalence for a sequence-to-sequence transformation A, the three variations are give by the ratios RmAx/RmAy.

Local Varieties and Asymptotic Equivalence [PDF]

open access: yesProceedings of the American Mathematical Society, 1962
1. Let o be a local domain and let a be an ideal of o that is primary for the maximal ideal m of o. If a is an element that is superficial of degree s for a (in the sense of [6, p. -i2 ]) and a,, * * *, at is a basis for c8, let o(a, a)=o[a,/a, * * *, at/a].

Asymptotically equivalent prediction in multivariate geostatistics

open access: yesBernoulli, 2022
Cokriging is the common method of spatial interpolation (best linear unbiased prediction) in multivariate geostatistics. While best linear prediction has been well understood in univariate spatial statistics, the literature for the multivariate case has been elusive so far.

Asymptotic charges in massless QED revisited: a view from spatial infinity

open access: yesJournal of High Energy Physics, 2019
Hamada and Shiu have recently shown that tree level amplitudes in QED satisfy an infinite hierarchy of soft photon theorems, the first two of which are Weinberg and Low’s theorems respectively.

Impulse Neuron and Cellular Neural Automaton are Asymptotically Equivalent

open access: yesМоделирование и анализ информационных систем, 2014
In the article, it is established the asymptotic equivalence of dynamics of the neural networks consisting of the impulse neurons and the neural networks built of the neural cellular automata of different kinds (autogenerators and detectors).
