On full equivalence logarithms of a sum and a maximal term of positive series of Taylor-Dirichlet type. (Ukrainian. English summary) Zbl 0948.30011

Summary: Conditions under which the asymptotic equality \[ \ln F(\sigma)\sim\ln\max\{a_{n}\exp(\sigma\lambda_{n}+h(\sigma)\beta_{n}) \colon n\geq 0\} \] holds as \(\sigma\to+\infty\) for functional series of the form \[ F(z)= \sum_{n=0}^{+\infty}a_{n}\exp\{\sigma\lambda_{n}+h(\sigma)\beta_{n}\} \] are proposed.
