Three-term exponential asymptotic for the maximal term of an entire Dirichlet series (in Ukrainian)

Conditions on the coefficients and the exponents of an entire Dirichlet series, under which for its maximal term the asymptotic equality $lnmu(sigma)=T_1e^{varrho_1sigma}+T_2e^{varrho_2sigma}+(tau+o(1))e^{varrhosigma}$ $(sigmato +infty)$ is valid, where $00$, $T_{2}in Rbackslash {0}$ and $tauin Rbackslash {0}$, are found.
