PROPERTIES FOR CERTAIN SUBCLASS OF ANALYTIC FUNCTIONS
摘要
For analytic functions f(z) normalized by f(0) = f'0(0) - 1 = 0 in the open unit disk U, a class A^k (β_1, β_2, β_3, β_4;λ) of function f(z) defined by (The equation is abbreviated), where D^k denote the Ruscheweyh differential operator of order k, k ∈ N_0 : = N ∪ {0} for some complex number numbers β_1, β_2, β_3, β_4 and for some real λ ＞ 0 is introduced. The object of the present paper is to obtain some interesting properties of function class A^k (β_1, β_2, β_3, β_4;λ). Our results generalize the results due to Uyanik et al. (2010) and Uyanik and Owa (2011).
