Magma V2.10-16 Patch Notes

Algebras¶

• An error which caused the Lie algebra function HighestWeightRepresentation to sometimes return incorrect answers has been fixed.

Geometry¶

• A bug coercing from a projective scheme into an affine ambient (and vice versa) has been fixed.

Groups¶

• A bug in distinguishing between SymmetricGroup(n) of types GrpPerm and GrpPermCox has been fixed.

Rings and Fields¶

• The inverse of the map returned by IsIsomorphic for absolute fields defined by non-monic polynomials was wrong. This has been fixed.
• A failure that sometimes occurred in the residue class field map for prime ideals in non-maximal orders has been fixed.
• An internal error caused when the div operator was used with orders of quadratic fields has been fixed.
• An error when forming the residue class field of an algebraic function field whose constant field is an algebraic function field of infinite degree has been fixed.
• Some minor memory problems in the p-adics have been fixed.
• A bug in BasisMatrix of non-simple equation orders of number fields has been fixed.
• A bug in Index of a infinite order of an algebraic function field has been fixed.
