**OreSys**: A Mathematica implementation of several algorithms for uncoupling systems of linear Ore operator equations¶

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

## Short Description¶

`OreSys`

is a Mathematica package for uncoupling systems of linear
Ore operator equations. It offers four algorithms for reducing systems
of differential or (q-)difference equations to higher order equations
in a single unknown variable.

The package has been developed by Stefan Gerhold, a former member of the RISC Combinatorics group.
