Can the fan of a decomposable toric vector bundle be computed in sage?
Given r Cartier divisors D1,...,Dr on a toric variety X we have a locally free sheaf
of rank r. Cox, Little, and Schenck outline an algorithm for constructing the fan of the corresponding vector bundle on page 337 of their book Toric Varieties. Is this algorithm a feature of sage? If not, has anyone written it down in sage?
