Feature #1582
Factorization in K(a,b)[x,y]
Description
Florian would like to have factorization of polynomial over a function field e.g. QQ(a,b)[x,y]
.
This would also permit implementation of primary decomposition for general ideals (not just 0-dim).

Presumably the following approach should work:
- map into
K[a,b,x,y]
after clearing denoms - discard any factors not involving
x,y
via a content computation - factorize in
K[a,b,x,y]
- map factors back into original ring
Looks easy! Well, not too horribly hard...
