摘要：A subclass A ( n , k ) of analytic functions f ( z ) in the open unit disk U is introduced. By means of the result due to Fukui and Sakaguchi (Bull. Fac. Edu. Wakayama Univ. Natur. Sci. 30:1-3, 1980), some interesting properties of f ( z ) in A ( n , k ) concerned with Ponnusamy and Karunakaran (Complex Var. Theory Appl. 11:79-86, 1989) are discussed.
