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.
