Uniqueness Of Special Analytic Functions Concerning Sharing Values

We study the problems of uniqueness of the exponential polynomials and uniqueness of meromorphic functions concerning sharing values in the general domains.The main results are as follows.(1)Let f(z)and g(z)be non-constant exponential polynomials with constant coefficients and ak(k = 1,2,3,4)be distinct points in finite complex plane.If there are four angular sectors ?k(k=1,2,3,4)of opening strictly gtreater than? in C,such that for k ?{1,2,3,4},f(z)and g(z)share value ak CM in domain ?k,then f(z)= g(z).(2)Let f(z)and g(z)be non-constant exponential polynomials with constant coefficients and ak{k = 1,2,3)be distinct points in finite complex plane.If there are there angular sectors ?k(k= 1,2,3)of opening strictly gtreater than ?in C,such that for k? {1,2,3},f(z)and g(z)share value ak CM in domain?k,then there is a one time rational function T(z)such that g(z)?T(f(z)).(3)Let f(z)and g(z)be non-constant exponential polynomials with constant coefficients.If there is an angular sector ? of opening strictly greater than?,such that f(z)and g(z)share {z?C:z7+z + 1 = 0} CM in domain ?,then f(z)? g(z).Moreover,we give a new method for the uniqueness of two non-constant meromorphic functions(analytic functions)in the general domain.
