Abstract: |
The main purpose of this paper is to investigate the growth of Dirichlet series with zero order which converges in the whole complex plane. By using the theory of complex series, we further study the growth of Dirichlet-Hadamard product of Dirichlet series with zero order under two different conditions. Some relationship theorems concerning logarithmic order and logarithmic type between Dirichlet series and its Dirichlet-Hadamard product are obtained, which are improvement and extension of previous results given by Kong. |
Key words: logarithmic order logarithmic type Dirichlet series Dirichlet-Hadamard product |
