Subordination and superordination properties of p -valent functions defined by a generalized fractional differintegral operator

Abstract For a generalized fractional differintegral operator associated with p- valent functions, we study different properties of differential subordination and superordination related to this operator.

Inclusion results for certain subclasses of p-valent meromorphic functions associated with a new operator

In this paper, we introduce new subclasses of p-valent starlike, p-valent convex, p-valent close-to-convex, and p-valent quasi-convex meromorphic functions and investigate some inclusion properties of these subclasses and investigate various inclusion properties and integral-preserving properties for the p-valent meromorphic function classes.MSC:30C45.
