7.7.12.0. facShift
Procedure from library ncfactor.lib (see ncfactor_lib).
- Usage:
- facShift(h); h a polynomial in the n'th shift algebra
- Return:
- list
- Purpose:
- compute all factorizations of a polynomial in the nth shift
algebra
- Theory:
- h is mapped to the $n$th Weyl algebra and then factorized
there. The factorizations are mapped back (S_n in subalgebra
of Weyl algebra).
- Assume:
- basering is the nth shift algebra
- Note:
- Every entry of the output list is a list with factors for one possible factorization.
