Again, regarding FT, why is it true that

Thanks.

Thanks guys. :-) I am not sure what the variation, V and the primitive period,G. Could someone kindly explain? Thanks again. –  4ier Sep 20 '11 at 13:38
    
Those 2 terms I mean in the context as in @Christian Blatter's Lemma stated in Giuseppe's link. –  4ier Sep 20 '11 at 13:43
