Uniform Asymptotic Expansions

Journal of the London Mathematical Society, 1949
Die Differentialgleichung der Bessel-Funktionen wird durch die Transformation \(w = \sqrt{\zeta} J_\nu(\lambda\sqrt{1-\zeta^2})\), \(u = \mathfrak{ArTg}\,\zeta - \zeta\) in die Form gebracht: \[ d^2w/du^2 + w\{- \nu^2 + (\zeta^{-2} - 1) [\tfrac54 \zeta^{-4}+ \tfrac14 \zeta^{-2} + \lambda^2 - \nu^2)]\} = 0, \tag{1} \] wo \(\lambda\) eine geeignet ...

Asymptotic expansions at work.

Insurance: Mathematics and Economics, 1995
Abstract 1. NORMAL APPROXIMATIONS It is routine among applied statisticians to use normal approximations. One of the most classical results being for the maximum likelihood estimate θ^ based on n i.i.d. observations from a density with expected information i(θ).

On Multivariable Asymptotic Expansions

SIAM Review, 1971
In this paper we consider the damped linear oscillator with small damping $\varepsilon $. We obtain uniform asymptotic expansions of the solution as $\varepsilon \to 0$ that are uniformly valid for all time $t \geqq 0$, by the multitime method. We show how to determine the expansion coefficients without resorting to intuitive arguments. This is done by

The Asymptotic Expansion

2017
In this chapter, we relax the homogeneous portfolio assumption, and we derive an asymptotic series expansion of the \(k{\text {th}}\)-to-default Q-factor in the non-homogeneous case. We also show how to compute the conditional aggregate default distributions that appear in the expansion using the convolution recursion algorithm.

Asymptotic expansion for splines

1983
The author extends some of the previous results on asymptotic expansions for interpolating splines obtained by \textit{T. R. Lucas} [SIAM J. Numer. Anal. 19, 1051-1066 (1982; Zbl 0519.41010)] and the author himself [Sci. Sin., Ser. A 26, 919-930 (1983; Zbl 0524.41006)].

Asymptotic expansions

1995
Abstract The following asymptotics related to solutions of the CHE can be studied: Asymptotics of solutions of the CHE in a neighbourhood of the irregular singularity at infinity with special emphasis on Stokes phenomena. Asymptotics of solutions of the CHE and of the monodromy matrices with respect to large values of parameters ...
