Sandwich Results for Certain Subclasses of Multivalent Analytic Functions Defined by Srivastava-Attiya Operator

Abstract

Abstract. In this paper, we obtain some applications of first order differential subordination and superordination results involving the operator J λ,p s,b for certain normalized p-valent analytic functions associated with that operator.
