Elliptic Curves over the Rational Field
New features:
- The improved bound (due to Samir Siksek) on the difference between
the naive and canonical heights of a point has been implemented.
This bound is now used internally for the group closure operation
and is accessible via SiksekBound.
- The Cremona database of elliptic curves now includes all curves of
conductor up to 20 000.
Bug fixes:
- A long-standing bug in the 2-descent for certain curves has
been fixed. Up to conductor 10 000 there were 14 curves
affected, the smallest being 903B3.
