In the present paper, we investigate some subordination and superordination preserving properties of analytic functions associated with the Srivastava-Khairnar-More integral operator defined on the space of normalized analytic functions in the open unit disk U. Several sandwich-type results associated with this transformation are derived. Some useful… (More)

Let A be the class of analytic functions in the open unit disk U . For complex numbers a, b and c (c 6= 0,−1,−2, ....), let I c be the operator defined on A by (I c (f))(z) = z2F1(a, b; c; z) ∗ f(z) where 2F1(a, b; c; z) is the Gaussian hypergeometric function. The function f in A is said to be in the class k − SP c if I a,b c (f) is a k-parabolic starlike… (More)

Emami Paper Mill Ltd. at Balgopalpur industrial area produces a huge amount of fly ash and waste water to the environment. The application of disposed fly ash and waste water in crop cultivation may reduce the problem to some extent. The aim of this study is to investigate the effects of direct land application of fly ash on plant growth and production of… (More)

In this paper subordination and inclusion relations are studied for some subclasses of multivalent meromorphic functions in the punctured unit disc having a pole of order p at the origin. The subclasses under investigation are defined through combinations and iterations of a meromorphic analogue of the Cho–Kwon–Srivastava operator for normalized analytic… (More)
