Computational Algebra Seminar: Donnelly -- Descent algorithms for elliptic curves

Speaker: Steve Donnelly
Title: Descent algorithms for elliptic curves, Part 2
Time & Place: 15:05-16:00, Thursday 17 June, Carslaw 173

Continuing from the previous talk, I will discuss obstructions
to descent, and the associated conjectures. I will also discuss
the problem of finding models of the covering curves with minimal
degree (as hyperelliptic curves in the case of 2-descnt), and the
obstruction to this.  Then I will describe 4-descent and 3-descent.
