摘要: Let   Ap(n)(p , n ∈   N   ={1,2,…}) denote   the   class  of  functions  of   the  form ...  analytic in the unit disc E ={z :|z |< 1}.By using the method of differential subordinations we give some sufficient conditions for a function f(z)∈ Ap(n)to be a certain subclass Rp(n,k)of p-valently close-to-convexity functions .

关键词: analytic functions, p-valently close-to-convexity functions, subordination
