#4695: [with patch, needs review] add support for pari's rnfidealdown
---------------------------+------------------------------------------------
Reporter: ncalexan | Owner: was
Type: enhancement | Status: new
Priority: major | Milestone: sage-3.2.2
Component: number theory | Keywords: relative rnf ideal down
---------------------------+------------------------------------------------
The attached patch adds support for pari's rnfidealdown. This is simple
but exposes a weakness in Sage's number field relativize() function, which
I address at the same time. Namely, relativize always constructs a new
base number field and embedding rather than (possibly) using an existing
one. The doctests are extensive and reveal (and document!) a bug in the
existing code.
