Notice that since ∣∣Z⅞τ (E⅛^χ3jit — Ex3jit) ∣∣4 ≤ τ (r)4 G (¾)4 by Assumption
6(iv), we have sup, ∣∣Z⅞feT (A¾y.⅛fe,i - Ex3kti) ∣∣4 ≤ (ʃθɪ τ (r)4 dr) supiG(¾)4
for к = 1,2, and 3. Therefore, by Lemma 10, we have
E KD3kτ (Ej^ix3k,i — Ex3k1i} K
(uniformly in i)
< ∞, for к = 1, 2, 3,
where τ3ι (r) = 0. So,
supE ∖∖D3τ (Eτz.x3,i - Ex3ji) ∣∣4 < ∞. (67)
Similarly, it follows that
sup sup E ∣∣Z⅛τ (E∏sx3 - E⅛)∣∣4 < ∞∙ (68)
