Abstract
In this article, we compute tables of values for the Riemann-Liouville
fractional derivative of the generalized polylogarithm functions considering parameter values µ = 3; 4; 5 and s =

. Several authors investigated such
functions and their analytic properties, but no work can be found in the literature for
the computation of their values. We perform numerical computations to evaluate
Riemann-Liouville fractional derivative of the generalized polylogarithm functions
for different values of the involved parameters. We validate the data obtained by
using our new mathematical model (given in the form of a difference equation)
and the known classical integral representations for µ = 3; 4; 5 and s =

is worth mentioning that for the positive values of parameter s =
