On a Subclass of Meromorphic Multivalent Functions Defined by Fractional Calculus Operators

, 2016
[[abstract]]In this paper, a new subclass of meromorphic multivalent functions is defined by making use of a fractional differ-integral operator. The coefficient estimates, and the radii of starlikeness and convexity, for this subclass are determined ...

Non-linear difference polynomials sharing a polynomial with finite weight

Ratio Mathematica
The uniqueness theory of meromorphic function mainly studies the conditions under which there exists only one function satisfying these conditions. The uniqueness theory of entire and meromorphic functions has grown up as an extensive sub-field of value ...

The Oscillation on Solutions of Some Classes of Linear Differential Equations with Meromorphic Coefficients of Finite [p,q]-Order

The Scientific World Journal, 2013
This paper considers the oscillation on meromorphic solutions of the second-order linear differential equations with the form f′′+A(z)f=0, where A(z) is a meromorphic function with [p,q]-order.

The asymptotic-behavior of Toeplitz determinants generated by the Laurent coefficients of a meromorphic function [PDF]

, 1985
By combining known results on the asymptotic behavior of Hankel and Toeplitz determinants we obtain expressions for det( f_{m + i - j} )_{i,j = 0}^n as n → ∞ and m = 0, ± 1, ± 2, .... The f_k are Laurent coefficients of a meromorphic function.

A uniqueness theorem for meromorphic functions

Математичні Студії
In this paper, we prove the uniqueness theorem for a special class of meromorphic functions on the complex plane $\mathbb{C}$. In particular, we study the class of meromorphic functions $f$ in the domain $\mathbb{C}\setminus K'$, where $K'$ is the finite

Uniqueness of a Meromorphic Function and its Differential Polynomial

, 2014
In this paper, we investigate the problem of uniqueness of a non-constant meromorphic function f and its differential polynomial Q[f] when they share two distinct, non-zero, small meromorphic function IM*, where we have taken the conditions N(r, f) = S(r,
