In this paper we investigate the Meijer -function
which, for certain parameter values, represents the Riemann-Liouville fractional integral of the Meijer-Nørlund function . The properties of this function play an important role in extending the multiple Erdélyi-Kober fractional integral operator to arbitrary values of the parameters which is investigated in a separate work, in
Fract. Calc. Appl. Anal., Vol. 21, No 5 (2018).
Our results for
include: a regularization formula for overlapping poles,
a connection formula with the Meijer-Nørlund function, asymptotic formulas around the origin and unity, formulas for the moments, a hypergeometric transform and a sign stabilization theorem for growing parameters.
