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.
