New description:
This ticket implements:
- Support for full subcategories defined by an axiom (Finite,
Infinite, Facade, Commutative, Associative, Unital,
Inverse, NoZeroDivisors, Division, FiniteDimensional, Connected,
WithBasis, Irreducible), and joins thereof:
{{{
sage: Groups() & Sets().Finite()
Category of finite groups
sage: Algebras(QQ).Finite() & Monoids().Commutative()
Join of Category of commutative algebras over Rational Field and
Category of finite monoids
sage: Rings().Division() & Sets().Finite()
Category of finite fields
}}}
- New categories:
- AdditiveSemigroups, AdditiveMonoids, AdditiveGroups
- DistributiveMagmasAndAdditiveMagmas
- MagmaticAlgebras (will replace Algebras in #15043)
- AssociativeAlgebras
- UnitalAlgebras
- Algebras of additive semigroups and monoids
- More mathematical rules:
- A subquotient of a finite set is a finite set
- The algebra of a finite set is finite dimensional
- The algebra of a commutative magma is commutative
- A finite division ring is a field
- ...
- Documentation:
- More documentation for IsomorphicObjects
- Complete revamping of sage.categories.primer
- Misc
- Use SubcategoryMethods to put the functorial constructions where
they belong. E.g. DualObjects, TensorProducts, and Graded are now
only defined for subcategories of Modules.
- More lazy imports, removed a bunch of unused imports, ...

Comment (by chapoton):
Hello Nicolas,
On 5.13.beta1, one got
{{{
application de trac_10963-more_functorial_constructions-nt.patch
patching file sage/combinat/integer_vector_weighted.py
Hunk #1 succeeded at 122 with fuzz 2 (offset -141 lines).
}}}
So I have refreshed your patch and uploaded a version with no hunks.
for the patchbot:
apply trac_10963-more_functorial_constructions-nt-refreshed.patch
trac_10963_doctest_correction-fc.patch trac_10963
