关于Lucas序列的Hurwitz型zeta函数

On the Hurwitz-type zeta function associated to the Lucas sequence

Lejla Smajlović, Zenan Šabanac, Lamija Šćeta

摘要:

在对$P$和$Q$的某些自然假设下,研究了由实数$P,Q$确定的第一类Lucas序列$U=\{U_n(P,Q)\}_{n\geq 0}$的θ函数和Hurwitz型zeta函数.我们推导了θ函数$θ_U(t)$的渐近展开式$t\downarrow 0$,并利用它得到了Hurwitz型zeta函数$ζ_{U}\left( s,z\right) =\sum\limits_{n=0}^{\infty }\left(z+U_{n}\right) ^{-s}$在整个复$s-$平面上的亚纯延拓.此外,我们确定了$ζ_{U}\left( s,z\right)$在半平面$\Re(s)\leq 0$的所有极点的残基。

英文摘要:

We study the theta function and the Hurwitz-type zeta function associated to the Lucas sequence $U=\{U_n(P,Q)\}_{n\geq 0}$ of the first kind determined by the real numbers $P,Q$ under certain natural assumptions on $P$ and $Q$. We deduce an asymptotic expansion of the theta function $θ_U(t)$ as $t\downarrow 0$ and use it to obtain a meromorphic continuation of the Hurwitz-type zeta function $ζ_{U}\left( s,z\right) =\sum\limits_{n=0}^{\infty }\left(z+U_{n}\right) ^{-s}$ to the whole complex $s-$plane. Moreover, we identify the residues of $ζ_{U}\left( s,z\right)$ at all poles in the half-plane $\Re(s)\leq 0$.
