Almost sure exponential stability of backward Euler–Maruyama discretizations for hybrid stochastic differential equations [PDF]

, 2011
This is a continuation of the first author's earlier paper [1] jointly with Pang and Deng, in which the authors established some sufficient conditions under which the Euler-Maruyama (EM) method can reproduce the almost sure exponential stability of the ...

Some sequence spaces and absolute almost convergence [PDF]

, 1984
The object of this paper is to introduce a new concept of absolute almost convergence which emerges naturally as an absolute analogue of almost convergence, in the same way as convergence leads to absolute convergence.

The topology of almost uniform convergence [PDF]

Pacific Journal of Mathematics, 1959
set S into a locally convex linear topological space F. Then a subset U of &(S, F) has property β over a subset A of S if it satisfies the following condition: for some neighborhood V of 0 in F it is true that for each finite subset {f19 ° ,/fc} of %>*(S, F) ~ U there is a finite subset {xlf x2, , xn] of A and a finite set of positive numbers {alf a2, •

Mean and Almost Everywhere Convergence of Fourier–Neumann Series [PDF]

, 1999
Let Jμ denote the Bessel function of order μ. The functions x−α/2−β/2−1/2Jα+β+2n+1(x1/2), n=0,1,2,…, form an orthogonal system in L2((0,∞),xα+βdx) when α+β>−1. In this paper we analyze the range of p, α, and β for which the Fourier series with respect to

Noncommutative strong maximals and almost uniform convergence in several directions

Forum of Mathematics, Sigma, 2020
Our first result is a noncommutative form of the Jessen-Marcinkiewicz-Zygmund theorem for the maximal limit of multiparametric martingales or ergodic means.

A Generalized of Sλ-I-Convergence of Complex Uncertain Double Sequences

Ingeniería y Ciencia, 2021
In this paper, we introduce the λI2 -statistically  convergence sequence concepts which are namely λI2 -statistically convergence almost surely (Sλ(I2) a.s.), λI2 -statistically convergence in measure, λI2 -statistically convergence in mean, λI2 ...

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).

Almost sure exponential stability of numerical solutions for stochastic delay differential equations [PDF]

, 2010
Using techniques based on the continuous and discrete semimartingale convergence theorems, this paper investigates if numerical methods may reproduce the almost sure exponential stability of the exact solutions to stochastic delay differential equations (

Quasi-almost convergence of sequences of sets [PDF]

, 2017
In this paper, we defined concepts of Wijsman quasi-almost convergence and Wijsman quasi-almost statistically convergence. Also we give the concepts of Wijsman quasi-strongly almost convergence and Wijsman quasi q-strongly almost convergence.
