Hi everybody...
I have a BIG problem that needs to solve:
if f(z) is an entire function with |f(z)<=B|z|^S, for all z in C,
(1) Should S be an integer and why,
(2) can we write f as: f(z)=A z^j, for some A in C, with |A|<=B.
please can one help me in soving this problem.

The conclusion should be that f(z) is a polynomial of degree no more than S.
Are you familiar with Liouville's theorem? Try to generalize the proof there to show that ak = 0 for k > S.
