Neighborhoods and Partial Sums of Certain Meromorphically Multivalent Functions
By making use of the familiar concept of neighborhoods of analytic functions, the author proves an inclusion relations associated with the (n, δ)−neighborhoods of a subclass Q k [p, α; A, B] which was introduced by Srivastava, Hossen and Aouf. The partial sums of the functions in Q k [p, α; A, B] are also considered.
متن کاملPartial Sums of Certain Meromorphic Functions
The purpose of the present paper is to establish some results concerning the partial sums of meromorphic starlike and meromorphic convex functions analogous to the results due to H. Silverman [J. Math. Anal. Appl. 209 (1997), 221-227]. Furthermore, we consider the partial sums of certain integral operator.

In this paper, we study the ratio of harmonic multivalent functions to its sequences of partial sums.

In this paper we establish some results concerning the partial sums of meromorphic p-valent starlike functions and meromorphic p-valent convex functions.
متن کاملNeighborhoods of Multivalent Functions
In this note, we introduce the new operator Dp(λ, q, η). Using this operator, we define the new subclasses of analytic and multivalent functions and for functions belonging to these classes, certain (n, δ)neighborhood properties are obtained. Mathematics Subject Classification: 30C45
