Magma V2.22-2 Patch Notes

Algebraic Function Fields¶

• An error now occurs instead of a crash when a non-order, constructed through incorrect setting of a parameter, is used.

Algebraic Number Fields¶

• An error now occurs instead of a crash when a non-order, constructed through incorrect setting of a parameter, is used.
• A bug has been fixed in MaximalOrder when the input number field has a non-monic or non-integral polynomial and the Ramification parameter is set.

Groebner Basis¶

• An error when computing truncated-degree Groebner basis over a finite field of size $2^k$ ($k>1$) has been fixed. Reported by G. Langeloh.
• A crash in Multiplicity for null sequences has been fixed. Reported by L. Los.

Group Algebras¶

• An error now occurs instead of a crash when attempting to construct a group algebra over an infinite matrix group.

Matrices¶

• A crash involving matrices over medium-size prime finite fields has been fixed. Reported by J. Rouse.

Modules¶

• A hang in computing an endomorphism ring of a general A-module in characteristic zero (the result of a maximal order computation) has been fixed. Reported by N. Bruin.
