Disjoint meromorphic functions and nonoscillatory differential systems

open access: yes, 1974
Conditions satisfied by disjoint meromorphic functions are obtained. These results are applied to nonoscillatory differential systems and disfocal differential equations.

Unicity Results Concerning of difference monomials of L-function and a meromorphic function

open access: yesRatio Mathematica
In this paper, we study the value distribution of $\mathcal{L}$-function in the extend Selberg class and a non-constant transcendental meromorphic $\mathsf{f}$ function with finitely many zeros of finite order, sharing a polynomial with its difference ...

Value Distributions and Uniqueness of Difference Polynomials

open access: yesAdvances in Difference Equations, 2011
We investigate the zeros distributions of difference polynomials of meromorphic functions, which can be viewed as the Hayman conjecture as introduced by (Hayman 1967) for difference.

On unique range sets of meromorphic functions in $\mathbb{C}^m$

open access: yes, 2007
summary:By considering a question proposed by F. Gross concerning unique range sets of entire functions in $\mathbb {C}$, we study the unicity of meromorphic functions in $\mathbb {C}^m$ that share three distinct finite sets CM and obtain some results ...

Super-optimal approximation by meromorphic functions. [PDF]

open access: yes, 1996
Let G be a matrix function of type m × n and suppose that G is expressible as the sum of an H∞ function and a continuous function on the unit circle. Suppose also that the (k – 1)th singular value of the Hankel operator with symbol G is greater than the ...

Ruscheweyh-type meromorphic harmonic functions

open access: yes
In this paper, we study classes of meromorphic harmonic functions defined by Ruscheweyh derivatives. In addition to finding certain analytic criteria, we obtain radii of starlikeness and convexity, and some topological properties for the defined classes ...
