Sharp bounds of third Hankel determinant for a class of starlike functions and a subclass of -starlike functions
Shagun Banga, S. Sivaprasad Kumar
Following the trend of coefficient bound problems in Geometric Function Theory, in the present paper, we obtain the sharp bound of for the class , of star…
A Novel Class of Starlike Functions
S. Sivaprasad Kumar, Shagun Banga
In the past several subclasses of starlike functions are defined involving real part and modulus of certain expressions of functions under study, combined by way of an inequality.…

S. Sivaprasad Kumar, Shagun Banga
Let be a non vanishing convex univalent function and be an analytic function in . We consider the differential subordination w…
On A Special Type Of Ma-Minda Function
S. Sivaprasad Kumar, Shagun Banga
This paper deals with a special type of Ma-Minda function introduced here with many fascinating facts and interesting applications. It is much akin in all aspects but differs by a…
The sharp bounds of the second and third Hankel determinants for the class SL^*
Shagun Banga, S. Sivaprasad Kumar
The aim of the present paper is to obtain the sharp bounds of the Hankel determinants H_2(3) and H_3(1) for the well known class SL^* of starlike functions associated with the righ…
