#6416: [with spkg and patch, needs review] Frobby for monomial ideals
-------------------------+--------------------------------------------------
Reporter: broune | Owner: tbd
Type: enhancement | Status: new
Priority: major | Milestone: sage-feature
Component: algebra | Keywords: monomial ideal, Hilbert series,
Alexander dual
Reviewer: | Author:

-------------------------+--------------------------------------------------
This spkg and patch updates the Frobby library that is already an optional
component of Sage, and gives it a Cython interface to a shared library
instead of the pexpect interface in the current Frobby spkg. It also
exposes more functionality. Functionality not currently in sage:
- Multigraded Hilbert-Poincare series
- Alexander dual of monomial ideals (already in the previous Frobby spkg)
- Maximal standard monomials of monomial ideals
- Irreducible decomposition of monomial ideals
- Optimization of any linear function over the maximal standard monomials
of a monomial ideal using branch-and-bound.
The patch applies cleanly to Sage 4.0.1, and the spkg is at
