Compute sheaf cohomology of coherent sheaves on toric varieties


ToricVarieties is a Gap4-package, which allows to compute properties of toric varieties. It is central to the ToricVarieties_project, which extends its functionality to computations with coherent sheaves on toric varieties.


To get the latest version of this GAP 4 package, clone ToricVarieties_project from github ( This completes the installation process.
