Bibasic Telescope

Short Description

Bibasic Telescope is a Mathematica implementation of a generalization of Gosper's algorithm to indefinite bibasic hypergeometric summation. The package has been developed by Axel Riese, a Ph.D. student of the RISC Combinatorics group.

Registration and Legal Notices

The source code for this package is password protected. To get the password send an email to Peter Paule. It will be given for free to all researchers and non-commercial users.

A Note on Encoded Files

This package contains one or more Mathematica input files which are encoded. Those files cannot be read or modified directly as plain text, but can be loaded into Mathematica just like any normal input file (i.e., with <<"file" or Get["file"]). There is no need (and also no way) to decode them by using additional software or a special key.

If loading an encoded file causes a syntax error, open it with a text editor and remove any blank lines at the beginning (for some reason your Mac could have inserted them silently...).

The Package

The Bibasic Telescope package consists of the Mathematica input file In addition some examples can be found in the Mathematica notebook accompanying the author's qZeil implementation

Important Upgrade Information

Beginning with version 2.2 the main function is called pqTelescope instead of qTelescope.
