From Wikipedia, the free encyclopedia
In mathematics , the incomplete polylogarithm function is related to the polylogarithm function. It is sometimes known as the incomplete Fermi–Dirac integral or the incomplete Bose–Einstein integral. It may be defined by:

Γ

.
{\displaystyle \operatorname {Li} _{s}(b,z)={\frac {1}{\Gamma (s)}}\int _{b}^{\infty }{\frac {x^{s-1}}{e^{x}/z-1}}~dx.}
Expanding about z=0 and integrating gives a series representation:

{\displaystyle \operatorname {Li} _{s}(b,z)=\sum _{k=1}^{\infty }{\frac {z^{k}}{k^{s}}}~{\frac {\Gamma (s,kb)}{\Gamma (s)}}}
where Γ (s) is the gamma function and Γ (s,x) is the upper incomplete gamma function . Since Γ (s,0)=Γ (s), it follows that:

{\displaystyle \operatorname {Li} _{s}(0,z)=\operatorname {Li} _{s}(z)}
where Lis (.) is the polylogarithm function.
