In this paper, we introduce two subclasses Eq ＊（φ） and ∑＊q,a（φ） of meromorphic functions f（z） for which qzDqf（z）/f（z）〈φ （z） and-（1-a/q）qzDqf（z）＋azqDq[zDqf（z）]/（1-a/q）f（z）-azDqf（z）〈φ（...In this paper, we introduce two subclasses Eq ＊（φ） and ∑＊q,a（φ） of meromorphic functions f（z） for which qzDqf（z）/f（z）〈φ （z） and-（1-a/q）qzDqf（z）＋azqDq[zDqf（z）]/（1-a/q）f（z）-azDqf（z）〈φ（z）,a ∈ C／（0,1],0〈q〈1, respectively. Sharp bounds for the Fekete-Szeg5 functional lal-tta21 of the above classes are obtained. Also, we consider some applications of the results obtained to functions defined by q-Bessel function.展开更多
In this paper, by making use of the Hadamard products, we obtain some subordination results for certain family of meromorphic functions defined by using a new linear operator.
Making use of the principle of differential subordination, we investigate some inclusion relationships of certain subclasses of p-valent analytic functions which are defined by Cho-Kwon Srivast ava Operator.
