On a New Class of p-Valent Meromorphic Functions Defined in Conic Domains. [PDF]

open access: yesScientificWorldJournal, 2016

Faber Polynomial Coefficient Estimates for Meromorphic Bi-Starlike Functions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2013
We consider meromorphic starlike univalent functions that are also bi-starlike and find Faber polynomial coefficient estimates for these types of functions. A function is said to be bi-starlike if both the function and its inverse are starlike univalent.

Applications of Higher-Order q-Derivative to Meromorphic q-Starlike Function Related to Janowski Function

open access: yesAxioms, 2022
By making use of a higher-order q-derivative operator, certain families of meromorphic q-starlike functions and meromorphic q-convex functions are introduced and studied.

Meromorphic starlike univalent functions [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1984
Let B be the class of functions ω(z) regular in |z| < 1 and satisfying ω(0) = 0, |ω(z)|<1 in |z|<1. We denote by P(A, B), −1 ≤ B < A ≤1, the class of functions p(z) = l+p1z+… regular in |z| < 1 and such that p(z) = [1+Aω(z)]/[1+Bω(z)] for some ω(z) ∈ Β.

Applications of Higher-Order Derivatives to the Subclasses of ‎Meromorphic Starlike Functions [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
In this paper, we introduce and study some new classes of multivalent (p -valent) meromorphically starlike functions involving Higher-Order derivatives. For these multivalent classes of functions, we derive several interesting properties including sharp ...
