Fuzzy Differential Subordination for Meromorphic Function

open access: yesAxioms, 2022
This paper is related to notions adapted from fuzzy set theory to the field of complex analysis, namely fuzzy differential subordinations. This work aims to present new fuzzy differential subordinations for which the fuzzy best dominant and fuzzy best ...

An Application of Differential Subordination [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We apply the general theory of differential subordination to obtain certian interesting criteria for ๐‘-valent starlikeness and strong starlikeness. Some applications of these results are also discussed.

Convolution and differential subordination [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
Let A denote the class of all functions f analytic in the open unit disc U with f(0) 0 f'(0)-1. Let h be any convex univalent analytic function on U with h(0) and Re h(z) > 0 in U. Let g A be fixed.

Applications of Subordination Chains and Fractional Integral in Fuzzy Differential Subordinations

open access: yesMathematics, 2022
Fuzzy differential subordination theory represents a generalization of the classical concept of differential subordination which emerged in the recent years as a result of embedding the concept of fuzzy set into geometric function theory.

On fuzzy differential subordination [PDF]

open access: yesMathematica Moravica, 2015
The theory of differential subordination was introduced by S.S. Miller and P.T. Mocanu in [2], then developed in many papers. In [1] the authors investigate various subordination results for some subclasses of analytic functions in the unit disc.

Third-Order Differential Subordination for Meromorphic Functions Associated with Generalized Mittag-Leffler Function

open access: yesFractal and Fractional, 2023
Using the results of third-order differential subordination, we introduce certain families of admissible functions and discuss some applications of third-order differential subordination for meromorphic functions associated with a linear operator ...

Some applications of a differential subordination [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
A number of interesting criteria were given by earlier workers for a normalized analytic function to be in the familiar class ๐”–* of starlike functions. The main object of the present paper is to extend and improve each of these earlier results.

Differential Subordination and Strong Differential Subordination for Continuous-Time Martingales and Related Sharp Inequalities

open access: yesAnnals of Probability, 1995
If \(X\) and \(Y\) are a pair of discrete martingales, suppose the difference sequence of \(X\) satisfies a pointwise domination with the corresponding sequence of \(Y\). Then one says that \(X\) is differentially subordinate to \(Y\). In the continuous parameter case the concept is in terms of their quadratic variations. Thus if \(X = \{X_t, {\mathcal

Differential Subordination and Superordination for Srivastava-Attiya Operator [PDF]

open access: yesInternational Journal of Differential Equations, 2011
Due to the well-known Srivastava-Attiya operator, we investigate here some results relating the p-valent of the operator with differential subordination and subordination. Further, we obtain some interesting results on sandwich-type theorem for the same.
