Ticket #31940 – Description
initial v2 1 This commit adds the first functionality for endomorphism rings of jacobians of genus 2 curves over Q. There is a new class `EndomorphismRing`, and two methods of this class: `is_absolutely_field` which determines whether or not the endomorphism algebra is a field; and `is_absolutely_trivial`, which determines whether or not the ring is just the integer ring Z. 2 3 Corresponding attributes have been added to the Jacobian of the hyperelliptic curve: `is_absolutely_simple` and `is_generic`. 4 5 This is needed for trac ticket #30837, and in that sense is blocking this other work.
