History

#1 Updated by Anna Maria Bigatti about 11 years ago

Now the function NewFreeModule(R, n) calls NewGradedFreeModule(R, n) when R is a polynomial ring (more precisely a SparsePolyRing).

The only relevant function now (just to see it works ;-) is
  • IsHomog for a MODULEELEM (working only if Rn is a graded free module)

I made some tests (and checked with Hilbert series) and it seems that shifts are done and OK. Added some documentation.

I think it is all done (naive resolutions work).
If some wrong aspect arises it'll become a new specific issue.
