In this paper,we discuss the following two patrs. The first ,the achievement of Dirichlet series in the right half-plane and in the complex plane for a few years are related.On the base of this, when the general exponential condition holds,and under the condition of lim = 1,I study infinite order Dirichlet series in the right half-plane and in the complex plane,and obtain the relations between the order of growth of Dirichlet series and conffieients.The second,we study the factorization of entire function in the condition of composition of functions, and obtain the necessary conditions of some pseudo-prime or E - pseudo - prime functions. |
