| Abstract |
It is proved that $\sum_{n=n_0}^{\infty}\frac{1}{n(\lambda_n+\beta_n)}<
+\infty$, provided the relation $\ln {F(\sigma)}\sim\ln {\mu(\sigma)}$
holds as $\sigma\to+\infty$ outside of some set for every function
$
F(\sigma)=\sum_{n=0}^{+\infty}a_n \exp(\sigma\lambda_n+\tau(\sigma)\beta_n),
$
where $a_n \ge 0 $ $(n \ge 0),$ $\{\lambda_n\}\subset \Bbb R_+$,
$\{\beta_n\}\subset
\Bbb R_+$, $\tau(\sigma)$ is a~fixed positive increasing function,
$\mu(\sigma)=\max\{a_n \exp(\sigma\lambda_n+\tau(\sigma)\beta_n):n \ge 0\}$.
