20:47 CoCoA-5 Support #1741 (In Progress): Documentation/Manual for HilbertFn

The manual for *@HilbertFn@* seems to need improvement.
_e.g._ @HilbertFn@ appears to work for modules too.
The e... John Abbott

20:44 CoCoA-5 Support #1079 (In Progress): CoCoAManual: AffHilbertFn accepts also ideal (correct?)

The manual now says *@(Poly or Quotient)Ring@*.
Is this sufficient/correct? From looking at the impl in @hp.cpkg5@... John Abbott

08:54 CoCoALib Bug #1740: MinGens gives non minimal gens *if some deg=0*

I wonder if it could be made to work by assuming that all indets with weight 0 actually have epsilon (an infinitesima... John Abbott

22:32 CoCoALib Design #1738: Suggestion about Graded polynomial rings

In CoCoA a poly ring has default term-order @degrevlex@ which we regard as 1-graded.
My suggestion means that by def... John Abbott

22:29 CoCoALib Design #1738 (New): Suggestion about Graded polynomial rings

If the user creates a graded polynomial ring, maybe CoCoA could actually create 2 polynomial rings:
* the one reques... John Abbott

12:50 CoCoALib Slug #1737 (In Progress): Homogenization of an ideal with ZZ^1-grading

(1) With a ZZ^1-grading I think it is enough to compute a "wdeg-rev" ReducedGBasis then "saturate" each element indep... John Abbott

16:01 CoCoALib Design #1736: Clean TmpGOperations, and remove Tmp prefix

I had to look in to *@TmpGoperations.C@* to find out about how CoCoALib implements ideal homogenization (and saturati... John Abbott

15:58 CoCoALib Design #1736 (New): Clean TmpGOperations, and remove Tmp prefix

How stable/clean is the code in *@TmpGOperations@*?
It forms a fairly central part of CoCoALib (and thus of CoCoA-5)... John Abbott

21:31 CoCoALib Design #1735: PushFront/PushBack without checks?

The suggestion arose from some new code for computing cyclotomic polynomials.
The coeff vec is computed quite quickl... John Abbott

21:29 CoCoALib Design #1735 (Rejected): PushFront/PushBack without checks?

Currently @PushFront@ and @PushBack@ check their args (correct coeffring, correct ppmonoid).
Should there also be un... John Abbott

22:05 CoCoA-5 Feature #1731: Verbosity level in CoCoA5

Not sure if it is really a good idea....
I remind you that it is possible to have global variables in packages. May... John Abbott
