... parts (1) and (4) of Lemma 2.11 give R −B + 1 < 0 and B − 1 < 0. Because the right-hand inequality is a consequence of Theorem 3.6, part (2), the proof is complete.  4.9. Proof of Theorem ... complete. The proof of the second part is similar. Note that the condition c ∈ (1/2, ∞), d ≥ c/(2c −1) of Lemma 2.11 is equivalent to the condition 1/c + 1/d ≤ 2 of Theorem 3.6. ...
