Description (last modified by )
This is a meta-ticket to keep track of the progress of integrating https://github.com/saraedum/mac_lane into Sage.
Fix bugs in Sage
There are a number of trivial bugs that get fixed by monkey-patches in https://github.com/saraedum/mac_lane/blob/master/__init__.py
- Conversion from a Function Field to its Constant Field #21872
- Conversion from a Function Field to its underlying Polynomial Ring #23166
- Coercions between Function Fields #23167
- Coercions are injective if the underlying map is #21879
- Ring homomorphisms from Fields are injective #21879
- Polynomial rings embed into their fraction fields #23185
The embedding of a ring into a polynomial ring over that ring is injective- p-adic rings embed into their fraction fields #23188
- Morphisms of number fields are injective #21879
- ZZ into QQ is injective #21879
- quotients of polynomial rings are injective/surjective #23190
- ZZ into a Number Field is injective #21879
- ZZ into an order of a Number Field is injective #21879
- ZZ does not map onto QQ #23186
ZpCA shifts are broken- add default implementation of inverse_of_unit() #23191
Add new features to Sage
New features that the code needs to work
- Factorization over iterated extensions of finite fields. #21996
principal_part() and sides() of a Newton Polygon(patch this in the calling code instead.)- (cached_in_argument_method #22034)
Make tests non-trivial
- (some_elements() should be non-trivial for number fields/orders) #23192
- (some_elements() should be non-trivial/deterministic for rational function fields and their extensions) #23193
- (some_elements() should be non-trivial for fraction_fields of polynomial rings) #23194
Add the valuation code to Sage
i.e., add these files https://github.com/saraedum/mac_lane to Sage.
