Patch release for Magma V2.28-23. Updated areas: Affine Algebras, Algebraic Number Fields, Polynomial Rings.

16 May 2025 3 areas

Affine Algebras

• The common over-structure of the field F of fractions of an affine algebra A with A itself is now returned as F, so (A.1 in F) now works. Issue reported by Taylor Dupuy.

Algebraic Number Fields

• A crash when constructing polynomial rings over embedded algebraic number fields has been fixed.

Polynomial Rings

• A bug where HasRoot sometimes incorrectly returned false for polynomials over algebraic number fields has been fixed.

• A crash in RationalReconstruction when given incompatible polynomials has been fixed.
