New description:
This bug tracks the current status of the toric varieties code and the
interdependence of new patches, which should be applied '''on top of Sage
4.7'''. Any (properly ordered) part of positively reviewed patches can be
merged at any time, there is no need to "bundle tickets."
'''Applied to the current Sage alpha/beta/rc'''
* #10943: Fan morphism fails on not full-dimensional fans
* #10140: Base sage.geometry.cone on the Parma Polyhedra Library (PPL)
* #10882: Add kernel fan to fan morphism
* #11302: Make it easier to construct a fan from a triangulation
* #10023: Compute Hilbert basis of cone
* #11200: Add fibration check to `FanMorphism`
'''Positively reviewed:'''
* #10529: dimension() and is_smooth() for algebraic subschemes of toric
varieties
* #11481: LLL for degenerate matrices crashes
* #10540: Spec and patches for singular affine toric varieties /
algebraic schemes.
* #11312: Speed up the computation of the Hilbert basis of a cone
These needs-review groups (separated by blank lines) can be applied
independently on top of the positively reviewed ones:
* #11392: Toric ideals over fraction fields
* #11385: Orbit closure as toric variety
* #11384: Construct the complex of a fan
* #11400: Add `PointCollection`
* #11429: Count integral points without PALP
