**SumCracker**: A Mathematica implementation of several algorithms for identities and inequalities of special sequences, including summation problems¶

This package is part of the RISCErgoSum bundle. See Download and Installation.

## Short Description¶

The SumCracker package contains routines for manipulating a large class of sequences (admissible sequences). It can prove identities and inequalities for these sequences, simplify expressions, evaluate symbolic sums, and solve certain difference equations.

SumCracker is developed for Mathematica 7 and might not run properly on earlier versions of Mathematica.

## Literature¶

To use the implementation it is sufficient to study the notebook demo.nb. It contains a few examples to start with.
