Asymptotic Density for Equivalence

open access: yesElectronic Notes in Theoretical Computer Science, 2005
AbstractIn this paper we study the asymptotic behavior of the fraction of true formulas against all formulas over k propositional variables with equivalence as the only connective in the language. We consider two ways of measuring the asymptotic behavior. In the first case we investigate the size of the tautology fraction of length n against the number

Asymptotic equivalence of double sequences

open access: yes, 2012
The goal of this paper is to present a four-dimensional matrix characterization of asymptotic equivalence of double sequences. This will be accomplished with the following notion of asymptotic equivalence of double sequences. Two double sequences are asymptotic equivalent if and only if P − limk,l xk,l yk,l = 1, where x and y are selected judicially ...

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.
