ALMOST SURE CONVERGENCE ON CHAOSES

open access: yesProceedings of the American Mathematical Society, 2019
International audienceWe present several new phenomena about almost sure convergence on homogeneous chaoses that include Gaussian Wiener chaos and homogeneous sums in independent random variables.

Polynomial asymptotic stability of damped stochastic differential equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2004
The paper studies the polynomial convergence of solutions of a scalar nonlinear It\^{o} stochastic differential equation\[dX(t) = -f(X(t))\,dt + \sigma(t)\,dB(t)\] where it is known, {\it a priori}, that $\lim_{t\rightarrow\infty} X(t)=0$, a.s.

Convergence in probability and almost sure with applications

open access: yesStochastic Processes and their Applications, 2001
A necessary and sufficient condition is given for the convergence in probability of a stochastic process {Xt}. Moreover, as a byproduct, an almost sure convergent stochastic process {Yt} with the same limit as {Xt} is identified. In a number of cases {Yt}

Almost Sure Convergence for the Maximum and the Sum of Nonstationary Guassian Sequences

open access: yesJournal of Inequalities and Applications, 2010
Let (Xn, n≥1) be a standardized nonstationary Gaussian sequence. Let Mn= max{Xk,1≤k≤n} denote the partial maximum and Sn=∑k−1nXk for the partial sum with σn= (Var Sn)1/2.

On the Almost Sure Rate of Convergence of Linear Stochastic Approximation Algorithms

open access: yesIEEE Transactions on Information Theory, 2004
The almost sure rate of convergence of linear stochastic approximation algorithms is analyzed in this correspondence. As the main result, it is demonstrated that their almost sure rate of convergence is equivalent to the almost sure rate of convergence ...

Almost Sure Convergence of Generalized $U$-Statistics

open access: yesAnnals of Probability, 1977
Almost sure convergence of generalized $U$-statistics and von Mises' differentiable statistical functions is studied with the help of the general $L \log L$ martingale convergence theorem.

Lpand almost sure convergence of a Milstein scheme for stochastic partial differential equations

open access: yesStochastic Processes and Their Applications, 2013
In this paper, Lp convergence and almost sure convergence of the Milstein approximation of a partial differential equation of advection-diffusion type driven by a multiplicative continuous martingale is proven.

Estimating Cumulative Distribution Function Using Gamma Kernel [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2022
In this article, we propose the gamma kernel estimator for the cumulative distribution functions with nonnegative support. We derive the asymptotic bias and variance of the proposed estimator in both boundary and interior regions and show that it is free
