Description

The function MakeGlobalHPPowerList(const DenseUPolyRing& P) in GlobalManager.C creates a list of polynomials.
Its ring (a DenseUPolyRing) should be easily accessible by users.

Which name should it have?
RingQQt?

AMB 2013-07-23: John Abbott wrote RingQQt(n) (unique copy), for n indeterminates.
It is not guaranteed to be the same ring as above, but it is a global ring which can be used for many purposes.

History

#1 Updated by Anna Maria Bigatti over 11 years ago

Currently it is available calling the function

  DenseUPolyRing StartPoincareQQt(int IndetsNo);

included in (include/)*../src/AlgebraicCore/TmpHilbertDir/TmpPoincareCPP.H*

IndetsNo is used for precomputing some powers of (1-x) -- used by the Hilbert algorithm.
