On the growth of the maximum modulus of an entire function depending on the growth of its central index
P. V. Filevych L'viv National University of Veterinary Medicine and Biotechnology, L'viv, Ukraine
Abstract:
Let $h$ be a positive function continuous on $(0,+\infty)$, $f(z)=\sum_{n=0}^\infty a_nz^n$ be an entire function, and $M_f(r)=\max\{|f(z)|\colon|z|=r\}$, $\mu_f(r)=\max\{|a_n|r^n\colon n\ge0\}$, and $\nu_f(r)=\max\{n\ge0\colon|a_n|r^n=\mu_f(r)\}$ be the maximum modulus, the maximal term, and the central index of the function $f$, respectively. We establish necessary and sufficient conditions for the growth of $\nu_f(r)$ under which $M_f(r)=O(\mu_f(r)h(\ln\mu_f(r)))$, $r\to+\infty$.
Keywords:
entire function, maximum modulus, maximal term, central index, order, lower order.
