Fuzzy Differential Subordination for Meromorphic Function Associated with the Hadamard Product [PDF]
Axioms, 2023 This paper is related to fuzzy differential subordinations for meromorphic functions. Fuzzy differential subordination results are obtained using a new operator which is the combination Hadamard product and integral operator for meromorphic function.

Application of Differential Subordinations to the Arithmetic–Geometric Means by Using an Operator [PDF]
Journal of MathematicsThis study investigates differential subordination involving arithmetic and geometric mean approaches associated with a previously introduced operator. While earlier studies considered cases where the dominant function was convex or linear, the present ...

Strong Differential Subordination to Briot-Bouquet Differential Equations
Journal of Differential Equations, 1994 Let p(z) be analytic in the unit disc D, let g(z) be convex in D, let ƒ(z) be analytic in D such that z(ƒ′(z)/ƒ(z)) is analytic and different from zero in D, and let α and β be complex numbers.

Annals 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 Results for Analytic Functions in the Upper Half-Plane [PDF]
Abstract and Applied Analysis, 2014 There are many articles in the literature dealing with differential subordination problems for analytic functions in the unit disk, and only a few articles deal with the above problems in the upper half-plane.
