摘要
( ) In this paper, we define a subclass of analytic functions by denote T beta H z, C(lambda) n (t) satisfying the following subordinate condition(1 - beta) C zf '(z)/ C / 1 + zf '' (z) 1 + beta-< f(z) f '(z) (1 - 2tz + z2)lambda, (1 ]where beta > 0, lambda > 0 and t E 2 , 1 . We give coefficient estimates and Fekete-Szego spacing diaeresis inequality for functions belonging to this subclass.
