| Feb 9, 2010 at 20:56 | comment | added | blt | The counterexample in the paper seems to give a counterexample to the question here too; it gives an example of an element of Sp(4,\Qbar) which, not being in the image of the exponential map when considered as an element of Sp(4,\C), cannot have all nth roots. | |
