Software

 

GENOM3CK- A library for solving the genus computation problem

  • GENOM3CK is a free library implemented in Axel and Mathemagix (i.e. in C++ using Qt Script for Applications, and Open Graphics Library).
  • Shortly, GENOM3CK contains operations from algebraic geometry, topology and knot theory on a plane complex algebraic curve. GENOM3CK was developed for supporting completely the symbolic-numeric algorithms for plane complex algebraic curves (i.e. algebraic link, Alexander polynomial, delta-invariant, Milnor number of a singularity, genus of the curve, etc). 
  • GENOM3CK -Now available for Mac OS X and Linux.
  1. Dependencies: Qt4 (Shortly, Qt is a cross-platform application and UI framework) and Axel (Shortly, Axel is a free algebraic geometric modeler for manipulating algebraic curves and surfaces).
  2. Download and installation instructions available at GENOM3CK homepage.
  3. For detailed information on the library and the symbolic-numeric algorithms which are implemented in the library, please browse the online documentation of GENOM3CK. This online documentation was created with TeXmacs.
  4. For detailed information concerning the released versions of the library and its main functionalities, please browse the webpage on VERSIONS and FUNCTIONALITIES of GENOM3CK
For any questions or suggestions on the library please feel free to contact: madalina.hodorog@oeaw.ac.at

 

Mathematica packages for computations in algebraic geometry

  • A package for computing the stereographic projection of a plane complex algebraic curve from the 4-dimensional space into the 3-dimenisional space. Click here for Stereographic projection.
  • A package for computing the domain for the stereographic projection of a plane complex algebraic curve from the 4-dimensional space into the 3-dimensional space. Click here for Domain.
  • A package for generating automatically XML files from Mathematica computations. Click here for Generate XML files.
  • HELP ON USING THE PACKAGES: After downloading the packages one has to put them in a directory where Mathematica can find them on its search path. To find the default search path, start Mathematica and execute the command $Path. Mathematica will list the directories that will be searched. Thus if you place the downloaded packages into one of these directories, you can use the command Needs["namepackage`"] to load the package. You can read more about using Mathematica packages here.
  • HELP ON USING THE PACKAGES: Here you can download a Mathematica sample file about using the packages.
  • These Mathematica packages were created for supporting partly the symbolic-numeric algorithms for plane complex algebraic curves.

For any questions or suggestions on the packages please feel free to contact: madalina.hodorog@oeaw.ac.at
