Papers

- Symbolic-Numeric Factorization of Differential Operators, 2022 [acm] [pdf] [bib]

- A Sage Package for the Symbolic-Numeric Factorization of Linear Differential Operators, 2021 [acm] [pdf] [bib]

Software

- Factorization of linear differential operators (developing code into a SageMath package named ore_algebra) [source]

How to use my code? (at least if you installed SageMath from source)

1) Open your terminal (where you want to download ore_algebra)

2) Type:

git clone https://github.com/a-goyer/ore_algebra -b facto

sage -pip install ore_algebra/

sage

3) In the Sage session, you could try:

sage: from ore_algebra.examples import ssw
sage: ssw.dop[1,0,0].factor()
[(16*t^3 - t)*Dt^2 + (80*t^2 - 5)*Dt + 48*t, t*Dt + 2]
