On Some Differential Operators Related to A Type of Meromorphic Univalent Functions

Tikrit Journal of Pure Science, 2023
The goal of this article is to introduce a class of a type of meromorphic function which defined by some differential operators. Then we study various properties of these operators such as, coefficient inequality, both of growth and distortion theorems,

A class of univalent functions with varying arguments

International Journal of Mathematics and Mathematical Sciences, 1992
f(z)=z+∑m=2∞amzm is said to be in V(θn) if the analytic and univalent function f in the unit disc E is nozmalised by f(0)=0, f′(0)=1 and arg an=θn for all n.

Distortion and covering theorems of pluriharmonic mappings

, 2017
The linear-invariant families of analytic functions make it possible to obtain well-known results to broader classes of functions, and are often helpful in obtaining simpler proofs along with new results.

Distortion theorems on the unit ball of a JB-triple [PDF]

, 2011
application/pdfLet B be the open unit ball of a JB*-triple. We prove distortion results for normalized convex mappings f : B → X which generalize various finite dimensional distortion theorems and improve some infinite dimensional ones.departmental ...

Embedding distortion analysis in wavelet-domain watermarking [PDF]

, 2019
Imperceptibility and robustness are two complementary fundamental requirements of any watermarking algorithm. Low strength watermarking yields high imperceptibility, but exhibits poor robustness. High strength watermarking schemes achieve good robustness

Sharp Results and Fluid Flow Applications for a Specific Class of Meromorphic Functions Introduced by a New Operator

Axioms
In this investigation, we introduce a new meromorphic operator defined by meromorphic univalent functions. A new class of meromorphic functions is introduced by this operator, which can generate several distinct subclasses depending on the values of its ...
