Never Let Me Tell You This Doesn’t Count

Ben Blum-Smith, on what provoked him to inquiry this week:

This is admittedly abstruse, but honestly what’s had my notebook out all week is trying to figure out what the Riemann surface of y^3-xy-x looks like. I think I’ve figured out how the sheets permute at the branch points, but I don’t think I’ll really be satisfied until I’ve in some way drawn a picture of the mapping of the y-plane to the x-plane, and I don’t see that happening without computational help.

I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.
