Maple and Singular

  1. Systems (Maple)
    Maple program used to test one hundred of linear systems of our paper:
    Quasi-homogeneous linear systems on P2 with base points of multiplicity 5.
  2. Quasi-homogeneous (Singular)
    with Luca Ugaglia,
    Singular program used to produce all the quasi-homogeneous special systems with given multiplicities.
  3. Tropical (Maple)
    Maple program for drawing tropical plane curves.
  4. StdClass (Maple)
    with Luca Ugaglia,
    Maple program for the study of classes on the blow-up of Pn at points in very general position.
  5. P1-n (Singular)
    with Elisa Postinghel,
    Singular programs used in the paper: arXiv:1105.2136v1.


  1. Toric-Fano
    with Michela Artebani,
    Magma functions used for our preprint Hypersurfaces in Mori dream spaces.
