A Principal Function Problem — Finding a meromorphic function with a given boundary behavior or singularity

, 2013
For a given meromorphic function s on an open subset A of an (open) Riemann surface R, we want to find a meromorphic function q on R such that both q/s and s/q are bounded on A.

On the algebraicity of germs of meromorphic functions

, 2023
In this article we prove that every germ of analytic meromorphic function at $(\mathbb{C}^{2},0)$ is equivalent, under the right composition by a germ of biholomorphism, to a germ of algebraic meromorphic function.

Two results on the value distribution of meromorphic functions

Open Mathematics
In this article, we prove two results on the value distribution of meromorphic functions. Using the theorem of Yamanoi, the first result gives a precise estimation of the relationship between the characteristic function of a meromorphic function and its ...

Meromorphic function sharing two sets with its difference operator

, 2012
We investigate the relationship between a meromorphic function f (z) and its difference operator when they share two sets, and give some interesting ...

A power of a combination of meromorphic function with its shift sharing small function with its derivative

, 2020
In this paper, we use the idea of normal family to investigate the situation when a power of a combination of transcendental meromorphic function with its shift shares small function with it's derivative and obtain three results which improve and ...

On Filling Circle of meromorphic Function

, 1995
考虑亚纯函数的零点或极点时，每个值点只取一次，而不计其重复度，本文证明了拟充满圆存在定理。This paper considers the Zero and pole of meromorphic Function and proves the pseudofilling Circle existence ...

Super-optimal approximation by meromorphic functions. [PDF]

, 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 ...

A New Class of Meromorphic Multivalent Functions Involving Certain Linear Operator

, 2016
[[abstract]]Making use of certain extended derivative operator of Ruscheweyh type, we introduce a new class Jp(; ; ) of meromorphic multivalent function in the punctured disk D = fz : z 2 C; 0 < jzj < 1g, and obtain some sucient conditions for the ...
