  • Ticket #15328 – Description

    initial v2  
    11This ticket implements filtered vector spaces and multi-filtered vector spaces (multiple filtrations of a single vector space). This is then used to implement Klyachko bundles.
    22
     3Mandatory fun example: There are 3 torus-equivariant deformations of the tangent bundle on the del Pezzo of degree 6:
     4{{{
     5sage: dP6 = toric_varieties.dP6()
     6sage: TX = dP6.sheaves.tangent_bundle()
     7sage: (TX * TX.dual()).cohomology(weight=(0,0), dim=True)
     8(1, 3, 0)
