Change log for Magma V2.10-14 (Released 3/8/2003)

Elliptic Curves

·An error that sometimes caused a crash when calculating of the trace of Frobenius for elliptic curves over fields GF(pn), where pn is quite large, has been fixed. Reported by Frederik Vercauteren.

Graphs

·A bug arising when deleting graphs and their vertices and edges has been fixed.

Lie Algebras

·A bug in the function SetExtraSpecialSigns has been fixed. Reported by Kasper Anderson.

Rings and Fields

·A bug in the factorization of ideals of number fields and function fields has been fixed.

·Some errors that occurred when creating divisors for elements of quadratic fields have been fixed.

·An oversight slowing the RayResidueRing map down has been corrected.

·The pre-image map for RayResidueRings for cyclotomic fields was broken.

·A memory management problem that arose when computing the Fourier expansion of the normalised Eisenstein function E2k(q) has been fixed. Reported by K Buzzard.

System

·Some debugging checks were accidentally included in the Windows 2.10-13 patch release. These have been removed.
