Algorithmic Methods for Special Functions by Computer Algebra
This is a now formally ended postdoc project (November 1999 until
October 2001) which was sponsored by
NWO, gebied Exacte Wetenschappen (project 613-06-565), was
coordinated by
Tom Koornwinder (KdV Institute,
Universiteit van Amsterdam) and
Nico Temme (CWI, Amsterdam),
and was performed by
Raimundas Vidunas, at present working at
National Kapodistrian University of Athens, Greece.

Rocky Mountain J. Math. 32 (2002), 919-936;
arXiv:math.CA/0005095.
An accompanying Maple worksheet

Maple procedure
infhsum.mpl (version 4.29, 30 November 2005)
for extension of Zeilberger's algorithm to nonterminating series
(by R. Vidunas).
There is an
accompanying Maple worksheet

by R. Vidunas.
The procedure and worksheets call
W. Koepf's hsum9.mpl.
This material has been tested in Maple 7, 8 and 9.
