We present a practical framework to prove, in a simple way, two-term asymptotic expansions for Fourier integrals

$$\begin{aligned} {{\mathcal {I}}}(t) = \int _{{\mathbb {R}}}(\mathrm{e}^{it\phi (x)}-1) \mathop {}\!\mathrm {d}\mu (x), \end{aligned}$$

where \(\mu \) is a probability measure on \({{\mathbb {R}}}\) and \(\phi \) is measurable. This applies to many basic cases, in link with Levy’s continuity theorem. We present applications to limit laws related to rational continued fraction coefficients.

有效估计与无限可整分布有关的某些振荡积分

我们提供一个实用的框架,以简单的方式证明傅立叶积分的两项渐近展开

$$ \ begin {aligned} {{\ mathcal {I}}}(t)= \ int _ {{\ mathbb {R}}}(\ mathrm {e} ^ {it \ phi(x)}-1) \ mathop {} \!\ mathrm {d} \ mu(x),\ end {aligned} $$

其中 \(\ mu \)\({{\ mathbb {R}}} \)上的概率度量, 而 \(\ phi \)是可测量的。这与Levy的连续性定理相关联,适用于许多基本情况。我们提出了一些应用来限制与有理连续分数系数有关的定律。
