一类广义Mathieu级数的渐近性

Asymptotics of some generalized Mathieu series

Stefan Gerhold, Zivorad Tomovski

摘要:

本文建立了由幂对数或阶乘序列定义的Mathieu型级数的渐近估计。通过Mellin变换,将问题映射为某个狄利克雷级数的奇异性,然后将其转化为原级数的渐近性。在幂对数序列的情况下,我们得到精确的一阶渐近。对于阶乘序列,梅林变换的自然边界使问题更具挑战性,但直接的初等估计给出了相当精确的渐近性。

英文摘要:

We establish asymptotic estimates of Mathieu-type series defined by sequences with power-logarithmic or factorial behavior. By taking the Mellin transform, the problem is mapped to the singular behavior of certain Dirichlet series, which is then translated into asymptotics for the original series. In the case of power-logarithmic sequences, we obtain precise first order asymptotics. For factorial sequences, a natural boundary of the Mellin transform makes the problem more challenging, but a direct elementary estimate gives reasonably precise asymptotics.
