[sage-support] Coordinate ring of `ToricVariety`
Hi all,
I am working with `ToricVariety` within Sage, and I have a question. Say I
define a toric variety as follows:
sage: PP = toric_varieties.WP([1, 3, 1]); PP
2-d toric variety covered by 3 affine patches
sage: PP.linear_equivalence_ideal()
Ideal (z0 - z2, z1 - 3*z2) of Multivariate Polynomial Ring in z0, z1, z2
over Rational Field
(The repr output of toric varieties is too simplified, but that's another
issue.) As seen in the second output, the "3" is definitely "somewhere
within the object". Thus I would expect the polynomial ring / coordinate
ring to also be a weighted one. However, that's not the case:
sage: PP.coordinate_ring().term_order()
Degree reverse lexicographic term order
sage: [g.degree() for g in PP.coordinate_ring().gens()]
[1, 1, 1]
Is this intended or should it return a weighted polynomial ring, something
like this?
sage: to = TermOrder("wdegrevlex", [1, 3, 1])
sage: R = PolynomialRing(QQ, 3, names="z", order=to)
sage: [g.degree() for g in R.gens()]
[1, 3, 1]

[sage-support] Re: Developer's guide and configure : the list of packages needs some updating
Many of these packages appeared in the 10.2 developer's guide only because of a bug in the script that generates this list. This is already fixed in the current beta; see https://deploy-livedoc--sagemath.netlify.app/html/en/installation/source#debian-ubuntu-package-installation Nevertheless, the package names should be corrected in build/pkgs//distros/debian.txt, as Dima explained. They only affect the experimental configuration explained in https://github.com/sagemath/sage/wiki/Sage-10.2-Release-Tour#configure---enable-system-site-packages-experimental and are otherwise just documentation.

Re: [sage-support] Developer's guide and configure : the list of packages needs some updating
package names per distribution are in build/pkgs//distros/ so you might want to adjust debian.txt files there and submit a PR with these changes On 23 January 2024 07:44:43 GMT, Emmanuel Charpentier wrote: > > >For installation from source on Debian, a few packages have incorrect names >in the Developer’s guide (and possibly in the configuration process files) : >| Replace | with | >++--| | >beautifulsoup4 | python3-bs4 | | cython | cython3 | | hatch-vcs | >python3-hatch-vcs | | importlib-resources | python3-importlib-resources | | >ipykernel | python3-ipykernel | | meson-python | python3-mesonpy (?) | | >python-fastjsonschema | python3-fastjsonschema | | >python-hatch-fancy-pypi-readme | python3-hatch-fancy-pypi-readme | | >python-tinycss2 | python3-tinycss2 | | rpy2 | python3-rpy2 | | >setuptools-scm | python3-setuptools-scm | | sphinxcontrib-websupport | >python3-sphinxcontrib.websupport | > >A question : are clang and clang-relatedpackages necessary or a “simple >recommendation” ?
