GAP Package
The BBGG package provides a GAP package to implement the Bernstein, Gelfand and Gelfand correspondence, in order to give several models for the derived category of coherent sheaves, over the projective space. First as a triangulated stable category over left modules over exterior algebras and the secondly by constructing the Beilinson monads.
The current version of this package is version 2022.08-01. For more information, please refer to the package manual. There is also a README.md file.
