Magma V2.14-6 Patch Notes

Associative Arrays¶

• Some crashes in associative arrays have been fixed. Reported by T. Ekedahl.

Groups¶

• A bug in the construction of inclusion and projection maps for direct products of sequences of pc-groups has been fixed. Reported by E. O'Brien.

Number Fields¶

• A bug in the computation of traces of elements in relative extensions of number fields defined by non-monic, non-integral polynomials has been fixed. The old code could return wrong answers. Reported by L. Wilson.
• A bug in the computation of inverses of isomorphisms of absolute simple number fields has been fixed. In certain situations where one of the input fields has a non-monic, non-integral defining polynomial the map returned was wrong. Reported by M. Kirschmer.

Polynomials¶

• A crash in multivariate GCD has been fixed (called from primary decomposition).
• Crashes in multivariate resultant have been fixed. Reported by M. Watkins.
