We study the structure of an n-homogeneous polynomial P:A_p(G_1)->A_p(G_2) between Figá-Talamanca–Herz algebras. Among other results, we show that there exist a proper affine map α:Y⊂ G_2->G_1 defined in an open coset Y of G_2 such that P(f)(y)=f(α(y))^n, ∀f∈A_p(G_1),y∈Y
when the locally compact groups G_1,G_2 are amenable and P is p-completely contractive, orthogonally additive and multiplicative, and preserves a right identity of A_p(G_1).
