Geometric properties of a domain with cusps
Shweta Gandhi, Prachi Gupta, Sumit Nagpal +1
For (even), the function maps the unit disk onto a domain bounded by an epicycloid with cusps. In this paper…
Marx-Strohhäcker theorem for Multivalent Functions
Prachi Gupta, Sumit Nagpal, V. Ravichandran
Some differential implications of classical Marx-Strohhäcker theorem are extended for multivalent functions. These results are also generalized for functions with fixed second coef…
Geometric Properties of Generalized Bessel Function associated with the Exponential Function
Adiba Naz, Sumit Nagpal, V. Ravichandran
Sufficient conditions are determined on the parameters such that the generalized and normalized Bessel function of the first kind and other related functions belong to subclasses o…
Briot-Bouquet differential subordination and Bernardi's integral operator
Kanika Sharma, Rasoul Aghalary, V. Ravichandran
The conditions on , , and are obtained for an analytic function defined on the open unit disc and normalized by to be subordinate to $(1+Az)…
Radius of starlikeness for some classes containing non-univalent functions
Shalu Yadav, Kanika Sharma, V. Ravichandran
A starlike univalent function is characterized by the function ; several subclasses of these functions were studied in the past by restricting the function $zf'(z)…
Starlikeness of Analytic Functions with Subordinate Ratios
Rosihan M. Ali, Kanika Sharma, V. Ravichandran
Let be a non-vanishing analytic function in the open unit disc with . Consider the class consisting of normalized analytic functions whose ratios , $g(z)…
