Let G_p be the Gowers complex space of characteristic p, B_p be theunitary closed ball and S_p be the unitary sphere of G_p. Then, any x in B_p can be written in a unique form as the sum of an element of the torus and an element of the unitary open ball of the Gowers space of characteristic p + k, for some k in N, which permit us to show that B_p does not have complex extreme points.
