18:04 Feature #992: Poly ring homomorphism to change ordering
- This may be just a special case of "extending a PPMonoid homomorphism" to a poly ring homomorphism.
It could also ... -
- It could be helpful to have an easy way of mapping from one poly ring to another which just changes the term ordering...

On several occasions I would have l... -

To see how slow the current code is, try the... -

- Is this now resolved? Or even in @feedback@? Perhaps change target version?

- Anders let us know by email (2016-11-28) about the problem in @gfanlib@.
I have already asked how a shell script c... -

We should either require that @gfanlib@ be newer than 0.6...

Note that e... -

In reference to my ... -

In fact the only operation no... -
- Now we have @SetVerbosityLevel@ it should be (almost) trivial.

- Added in CoCoA-5. Fantastic!
22 Nov 2016

- I still like the idea of an iterator, but it would be hard to "export" the notion to CoCoA-5. Maybe that does not ma...
-
- Added *@SmallestNonDivisor@* to @NumTheory@; also available in CoCoA-5.
Updated doc for @NumTheory@.
Still to do: ... -

Combining this with *@--with-cxxflags=@* sh...

- OK, we can try with the script (base)name at the end of the message. It shouldn't take too long to make the change.
