| Apr 6, 2010 at 5:56 | comment | added | Kevin Buzzard | I'm going to say something stupid. If f_ab induces an isomorphism f of p-divisible groups then surely the degree of f_ab is a rational number prime to p and so it's an isomorphism in the category of ab vars up to prime-to-p isogeny? I am just drawing my intuition from C, but replacing in my mind the physical points of p-power order (which don't tell you enough) by the Dieudonne module (which does). | |
