In 1948 he moved to New York and, hearing that I.B.M. was hiring mathematicians, obtained a job there as a researcher.
Many mathematicians applied them to obtain applications in analytic number theory, harmonic analysis, theoretical physics, equidistribution of Hecke points on a family of homogeneous varieties, and cohomology.
As regards the various properties of (zeta(s)), many mathematicians have studied them and obtained abundant research results.
This theory started with the classical works of Sturm and Kneser, and still attracts the attention of many mathematicians as much for the interesting results obtained as for their various applications.
During the time many mathematicians have studied on this problem and have obtained some results (see [10 19] and [20]).
As a model to describe these phenomena, the Cahn-Hilliard equation has intrigued many mathematicians' interests, and many good results [8 11] were obtained, such as the global existence, the asymptotic behavior, the stability of the solution of the Cahn-Hilliard equation, and so on.
As a result, many mathematicians show strong interest in fractional differential equations and many wonderful results have been obtained.
Many mathematicians were interested in the value distribution of different expressions of meromorphic functions and obtained lots of important theorems (see e.g. [1, 6 8]).
In the past few decades, many mathematicians studied the growth and value distribution of the analytic (entire) function defined by Dirichlet series and obtained lots of interesting results (see [1 9]).
The research on the value distribution of q meromorphic function is very active in the field of complex analysis; many mathematicians had done a lot of works in this project by using the Nevanlinna value distribution theory and obtained many famous results, such as the Picard theorem, Julia direction, Borel theorem, Borel direction, Hayman theorem, Yang-Zhang theorem, and so on (see [3 12]).
