Asymptotic Estimates of Stirling Numbers [PDF]

open access: yesStudies in Applied Mathematics, 1993
New asymptotic estimates are given of the Stirling numbers and , of first and second kind, respectively, as n tends to infinity. The approximations are uniformly valid with respect to the second parameter m.

Asymptotic Comparison of Parameters Estimates of Two-parameter Weibull Distribution

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The Weibull distribution is frequently applied in various fields, ranging from economy, business, biology, to engineering. This paper aims at estimating the parameters of two-parameter Weibull distribution are determined.

Recovery problem for a singularly perturbed differential equation with an initial jump

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
The article investigates the asymptotic behavior of the solution to reconstructing the boundary conditions and the right-hand side for second-order differential equations with a small parameter at the highest derivative, which have an initial jump ...

On Asymptotically Efficient Recursive Estimation

open access: yesThe Annals of Statistics, 1978
Stochastic approximation procedures were shown by Sakrison to become asymptotically efficient estimators when used to minimize the Kullback-Leibler information, if certain conditions hold. Further results in this direction were obtained by Nevel'son and Has'minskij.

The Asymptotic Behaviours of a Class of Neutral Delay Fractional-Order Pantograph Differential Equations

open access: yesAdvances in Mathematical Physics, 2017
By using fractional calculus and the summation by parts formula in this paper, the asymptotic behaviours of solutions of nonlinear neutral fractional delay pantograph equations with continuous arguments are investigated.

Sharp asymptotic estimates for vorticity solutions of the 2D Navier-Stokes equation

open access: yesElectronic Journal of Differential Equations, 2008
The asymptotic dynamics of high-order temporal-spatial derivatives of the two-dimensional vorticity and velocity of an incompressible, viscous fluid flow in $mathbb{R}^2$ are studied, which is equivalent to the 2D Navier-Stokes equation.
