> | ### D.15.9 gitfan_lib Library: gitfan.lib Purpose: Compute GIT-fans. Authors: Janko Boehm boehm@mathematik.uni-kl.de Simon Keicher keicher@mail.mathematik.uni-tuebingen.de Yue Ren ren@mathematik.uni-kl.de Overview: This library computes GIT-fans, torus orbits and GKZ-fans. It uses the package 'gfanlib' by Anders N. Jensen and some algorithms have been outsourced to C++ to improve the performance. Check https://github.com/skeicher/gitfan_singular for updates. Procedures:
> D.15.9.1 afaces |  | Returns a list of intvecs that correspond to all a-faces
> D.15.9.2 gitCone |  | Returns the GIT-cone around the given weight vector w
> D.15.9.3 gitFan |  | Returns the GIT-fan of the H-action defined by Q on V(a)
> D.15.9.4 gkzFan |  | Returns the GKZ-fan of the matrix Q
> D.15.9.5 isAface |  | Checks whether intvec corresponds to an ideal-face
> D.15.9.6 orbitCones |  | Returns the list of all projected a-faces
