Examining the behavior of parametric convex operators on a certain set of analytical functions [PDF]

MethodsX
Mathematical operators that maintain convex functional combinations involving at least one parameter are called parametric convex operators (PCOs) on analytic function spaces.

New Subclass of Analytic Function Involving q-Mittag-Leffler Function in Conic Domains

Journal of Function Spaces, 2022
In this paper, we formulate the q-analogus of differential operator associated with q-Mittag-Leffler function. By using this newly defined operator, we define a new subclass k−USq,γmα,β, of analytic functions in conic domains.

Regularization of distributions

International Journal of Mathematics and Mathematical Sciences, 1998
We give a simple necessary and sufficient condition for the existence of distributional regularizations. Our results apply to functions and distributions defined in the complement of a point, in one or several variables.

On the order of convolution consistence of the analytic functions with negative coefficients [PDF]

Mathematica Bohemica, 2017
Making use of a modified Hadamard product, or convolution, of analytic functions with negative coefficients, combined with an integral operator, we study when a given analytic function is in a given class. Following an idea of U. Bednarz and J. Sokół, we

Application of subordination and superordination for multivalent analytic functions associated with differintegral operator

AIMS Mathematics, 2023
The results from this paper are related to the geometric function theory. In order to obtain them, we use the technique based on the properties of the differential subordination and superordination one of the newest techniques used in this field, we ...

Some geometric properties of certain meromorphically multivalent functions associated with the first-order differential subordination

AIMS Mathematics, 2021
A new subclass $\mathcal{G}_n(A,B,\lambda)$ of meromorphically multivalent functions defined by the first-order differential subordination is introduced. Some geometric properties of this new subclass are investigated.

On a subclass of starlike functions associated with a vertical strip domain

Journal of Inequalities and Applications, 2019
In this paper, we consider a subclass of starlike functions associated with a vertical strip domain. We obtain several results concerned with integral representations, convolutions, and coefficient inequalities for functions belonging to this class ...

Real analytic functions and monomial curves [PDF]

arXiv, 2023
We show that a function is real analytic at the origin iff it is arc-analytic, has a subanalytic graph, and its restriction to every monomial curve is analytic. This complements recent results of Kucharz and Kurdyka.
