VL - 4 IS - 1 SE - Scientific articles DO - UR - https://journals.pnu.edu.ua/index.php/cmp/article/view/2402 SP - 28–35 AB - <p>Let $\Phi$ be a convex function on $[x_0,+\infty)$ such that $\frac{\Phi(x)}x\to+\infty$, $x\to+\infty$, $\displaystyle f(z)=\sum_{n=0}^\infty a_nz^n$ is a transcendental entire function, let $M(r,f)$ be the maximum modulus of $f$ and let $$ \rho_\Phi(f)=\varlimsup_{r\to +\infty}\frac{\ln\ln M(r,f)}{\ln\Phi(\ln r)},\quad c_{\Phi}=\varlimsup_{x\to +\infty}\frac{\ln x}{\ln\Phi(x)},$$ $$d_{\Phi}=\varlimsup\limits_{x\to +\infty}\frac{\ln\ln\Phi'_+(x)}{\ln\Phi(x)}. $$ It is proved that for every transcendental entire function $f$ the generalized order $\rho_\Phi(f)$ is independent of the arguments of the coefficients $a_n$ (or defined by the sequence $(|a_n|)$) if and only if the inequality $d_{\Phi}\le c_{\Phi}$ holds.</p> ER -
