... that m k n < | a n | . 3. Proof of the theorem Proof of Theorem 1.1.Letm =min |z|=k |p(z)|. If p( z)hasazeroon|z|=k,thenm = 0 and the result follows from Lemma 2.8. Henceforth, we suppose that all the zeros of p(z) ... k. But this result contradicts the fact that |a 1 |>k. Hence, the polynomial D α 1 p(z) must be of degree (n - 1). On the other hand, since all t...
