Subclasses of Multivalent Meromorphic Functions with a Pole of Order p at the Origin

Mathematics, 2022
In this paper, we carry out a systematic study to discover the properties of a subclass of meromorphic starlike functions defined using the Mittag–Leffler three-parameter function.

On Certain Classes of p-Valent Functions by Using Complex-Order and Differential Subordination

International Journal of Mathematics and Mathematical Sciences, 2010
The aim of the present paper is to study the p-valent analytic functions in the unit disk and satisfy the differential subordinations z(Ip(r,λ)f(z))(j+1)/(p-j)(Ip(r,λ)f(z))(j)≺(a+(aB+(A-B)β)z)/a(1+Bz), where Ip(r,λ) is an operator defined by Sălăgean ...

Sakaguchi type functions defined by balancing polynomials [PDF]

summary:The class of Sakaguchi type functions defined by balancing polynomials has been introduced as a novel subclass of bi-univalent functions. The bounds for the Fekete-Szegö inequality and the initial coefficients $\vert a_{2}\vert $ and $\vert a_{3}\

The second Hankel determinant and the Fekete-Szegö functional for a subclass of analytic functions by using the q-Sălăgean derivative operator

Alexandria Engineering Journal
The current study’s researchers create a new family of analytic functions in the open unit disk Λ by generalizing the q-difference operator. Our study lays a foundational understanding of the behavior of this functions.

Coefficient estimates and Fekete-Szegö problem for some classes of univalent functions generalized to a complex order

Demonstratio Mathematica
In this article, we determine coefficient estimates and study the Fekete-Szegö problem for classes Λn(b){\Lambda }_{n}\left(b) and Λnc(b){\Lambda }_{n}^{c}\left(b), where bb is a nonzero complex order.
