Jun 14, 2013 at 20:25 comment added Felipe Voloch Yes. This is the finite abelian descent obstruction. It's been conjectured that it's the only obstruction to the existence of rational points.
Jun 14, 2013 at 20:09 comment added Will Sawin This is inspired by work of Manjul Bhargava on hyperelliptic curves. I guess this is the universal descent obstruction for finite abelian groups?
Jun 14, 2013 at 19:17 comment added stankewicz Is this inspired at all by the descent obstruction to rational points?
