This article presents several findings regarding second and third-order differential subordination of the form: …
Higher order differential subordinations for certain starlike functions
Neha Verma, S. Sivaprasad Kumar
In this paper, we employ a novel second and third-order differential subordination technique to establish the sufficient conditions for functions to belong to the classes $\mathcal…
Coefficient problems for starlike functions associated with a petal shaped domain
S. Sivaprasad Kumar, Neha Verma
In the present investigation, we consider a subclass of starlike functions associated with a petal shaped domain, recently introduced and defined by $$\mathcal{S}^{*}_ρ:=\{f\in \ma…
A Conjecture on For Certain Starlike Functions
Neha Verma, S. Sivaprasad Kumar
We prove a conjecture concerning the third Hankel determinant, proposed in ``Anal. Math. Phys., https://doi.org/10.1007/s13324-021-00483-7", which states that is…
