Input Form





PolyLog[\[Nu], z] == Gamma[1 - \[Nu]] (-(z - 1))^(\[Nu] - 1) (1 + ((1 - \[Nu])/2) (z - 1) + ((-2 - \[Nu] + 3 \[Nu]^2)/24) (z - 1)^2 + \[Ellipsis]) + Zeta[\[Nu]] + Zeta[\[Nu] - 1] (z - 1) + (1/2) (Zeta[\[Nu] - 2] - Zeta[\[Nu] - 1]) (z - 1)^2 + \[Ellipsis] /; !(Element[\[Nu], Integers] && \[Nu] > 0)
