A generalization of slowly varying functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1986
This note establishes that if the main part of the definition of a slowly varying function is relaxed to the requirement that lim sup x → ∞ ψ ( λ x ) / ψ ( x ...

Very slowly varying functions. II [PDF]

open access: yesColloquium Mathematicum, 2009
This paper is a sequel to both Ash, Erdos and Rubel AER, on very slowly varying functions, and BOst1, on foundations of regular variation. We show that generalizations of the Ash-Erdos-Rubel approach -- imposing growth restrictions on the function h, rather than regularity conditions such as measurability or the Baire property -- lead naturally to the ...

Generalization of the Regularization Method to Singularly Perturbed Integro-Differential Systems of Equations with Rapidly Oscillating Inhomogeneity

open access: yesAxioms, 2021
In this paper, we consider systems of singularly perturbed integro-differential equations with a rapidly oscillating right-hand side, including an integral operator with a slowly varying kernel.

A Seneta's Conjecture and the Williamson Transform [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
Considering slowly varying functions (SVF), %Seneta (2019) Seneta in 2019 conjectured the following implication, for $\alpha\geq1$,$$\int_0^x y^{\alpha-1}(1-F(y))dy\textrm{\ is SVF}\ \Rightarrow\ \int_{0}^x y^{\alpha}dF(y)\textrm{\ is SVF, as $x\to\infty$

On the lateral vibrations of an elastic rod with varying compressive force [PDF]

open access: yesTheoretical and Applied Mechanics, 2004
We study lateral vibration of a simply supported axially compressed elastic rod with rotary inertia. The axial force is assumed to be a function of time. Stability of the solution is examined.

On the stability of a class of slowly varying systems

open access: yesJournal of Inequalities and Applications, 2018
Slowly varying systems are common in physics and control engineering and thus stability analysis for those systems has drawn considerable attention in the literature. This paper uses the “frozen time approach” to derive Lyapunov inequality conditions for

Differences of Slowly Varying Functions

open access: yesJournal of Mathematical Analysis and Applications, 2000
A positive non-decreasing function \(F\) belongs to the class \(\text{O}\Pi^+\) if \(\limsup(t\to\infty)(F(st)- F(t))= M(s)\) is finite for every \(s> 1\). Given a non-decreasing slowly varying function \(L\), if, whenever it is written as a sum \(L= F+G\) of two non-decreasing functions, both \(F\) and \(G\) are slowly varying, \(L\) is said to have ...

The Marcinkiewicz–Zygmund-Type Strong Law of Large Numbers with General Normalizing Sequences under Sublinear Expectation

open access: yesMathematics, 2023
In this paper we study the Marcinkiewicz–Zygmund-type strong law of large numbers with general normalizing sequences under sublinear expectation. Specifically, we establish complete convergence in the Marcinkiewicz–Zygmund-type strong law of large ...

Very slowly varying functions

open access: yesAequationes Mathematicae, 1972
Let \(\varphi\) be a positive non-decreasing real valued function defined on \([0, \infty)\), and let \(f\) be any real valued function defined on \([0, \infty)\). We say that \(f\) is \(\varphi\)-slowly varying if \(\varphi (x)[f(x+ \alpha)-f(x)] \to 0\) as \(x \to \infty\) for each \(\alpha\). We say that \(f\) is uniformly \(\varphi\)-slowly varying
