On a Subclass of Meromorphic Multivalent Functions [PDF]
, 2015 . In this paper, we introduce a new class of meromorphic multivalent functions in the puncturedunit discU ∗ = z ∈ C: 0 < z < 1. We obtain various resultsincluding coefficients inequality, convex set, radius of starlikeness and convexity, δ ...

Multivalent functions and QK spaces
International Journal of Mathematics and Mathematical Sciences, 2004 We give a criterion for q-valent analytic functions in the unit disk to belong to QK, a Möbius-invariant space of functions analytic in the unit disk in the plane for a nondecreasing function K:[0,∞)→[0,∞), and we show by an example that our condition is

Geometric Properties and Neighborhood for Certain Subclasses of Multivalent Functions [PDF]
, 2017 By using the two existing operators, we have defined an operator, which is an extension for them. In this paper, first the operator is introduced. Then, using this operator, the subclasses of multivalent functions are defined.

Salagean-type harmonic multivalent functions defined by q-difference operator [PDF]
, 2022 We introduce a new subclass of Salagean-type harmonic multivalent functions by using q-difference operator. We investigate sufficient coefficient es-timates, distortion bounds, extreme points, convolution properties and neighbor-hood for the functions ...

A certain q-Ruscheweyh type derivative operator and its applications involving multivalent functions
Advances in Difference Equations, 2021 In the present paper, by using the concept of convolution and q-calculus, we define a certain q-derivative (or q-difference) operator for analytic and multivalent (or p-valent) functions.

Certain Results on Fuzzy p-Valent Functions Involving the Linear Operator
Mathematics, 2023 The idea of fuzzy differential subordination is a generalisation of the traditional idea of differential subordination that evolved in recent years as a result of incorporating the idea of fuzzy set into the field of geometric function theory.

Conformable differential operators for meromorphically multivalent functions
Concrete Operators, 2021 We define a conformable diff-integral operator for a class of meromorphically multivalent functions. We show that this conformable operator adheres to the semigroup property.

Families of Meromorphic Multivalent Functions Associated with the Dziok-Raina Operator
International Journal of Analysis and Applications, 2013 Making use a linear operator, which is defined here by means of the Hadamard product (or convolution), involving the Wright’s generalized hypergeometric function , we introduce two novel subclassesP p(q,s,α1;A,B,λ) andP+p(q,s,α1;A,B,λ) of meromorphically

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
