The ore_algebra package provides an implementation of Ore algebras for Sage.
The main features for the most common instances include basic arithmetic and
actions; gcrd and lclm; D-finite closure properties; natural transformations
between related algebras; guessing; desingularization; solvers for polynomials,
rational functions and (generalized) power series.
