Automorphisms of numerical Godeaux surfaces with torsion of order 3 or more

Author: Stefano Maggiolo

• The paper on arXiv.
• The program consists of four Python sources:
  • GAC that stands for GodeauxAutomorphismsComputer;
  • LMPS that stands for LinearModularParametricSystems.
  • GAPI that stands for GAPInterface.
  • MVS that stands for Matrice and VectorSpace.
  To run, it needs GAP and sympy (version ≥ 0.6.4).
• Program's output for torsion of order five, four, three.
• GAP sources to compute centralizers for torsion of order five and four.
