Hadamard product of certain meromorphic univalent functions

Partial sums for certain classes of meromorphic functions

“…Note that when α = 0, Theorem 2.1 and Theorem 2.2 reduce to Theorem 2.2 and Theorem 2.1 in [5] respectively. Further, we note that these sufficient conditions are also necessary for functions of the form (1) when α = 0, A = 2µ − 1, B = 1 with positive or negative coefficients ( [1,2,3]).…”

“…The class Σ 0 ≡ Σ, was studied by many authors (see [1,2,3,4,5]). Note that the authors defined and studied the class Σ α for normalized analytic functions in an open disk (see [6,7]).…”

Generalizations of Hadamard Products of Certain Meromorphic Univalent Functions With Positive Coefficients

“…The classes Σ5^(α) and ΣΚι(α) have been extensively studied by Pommerenke [7], Clunie [2], Kaczmarski [4], Royster [8], Miller [5], Juneja and Reddy [3] and Mogra [6] and others.…”

Some sufficient conditions for certain class of meromorphic multivalent functions involving Cho-Kwon-Srivastava operator

“…k (α) and c (α) are subclasses of consisting of meromorphic univalent functions which are respectively starlike, convex and close-toconvex of order α (0 ≤ α < 1). For recent expository work on meromorphic functions see( [5,7,11,14,16]).…”
