Apr 29, 2012 at 15:24	comment	added	Andrea Mori		@Kevin Buzzard: I actually like the idea of calling it $A^{(1/p)}$! I'm sort of surprised, though, that there is no standard notation for it, like if this object had not been given much consideration.

Apr 29, 2012 at 13:06	comment	added	Kevin Buzzard		I guess you could call it $A^{(1/p)}$? Of course $A^{(p)}$ makes sense over any scheme where $p=0$ but $A^{(1/p)}$ relies on your base being e.g. a perfect field, so it won't come up as much I guess.
