Estimates for initial coefficients of certain bi-univalent functions
Vibha Madaan, Ajay Kumar, V. Ravichandran
Estimates are obtained for the initial coefficients of a normalized analytic function in the unit disk such that and the analytic extension of to $\ma…
Radii of Starlikeness and Convexity of Bessel Functions
Vibha Madaan, Ajay Kumar, V. Ravichandran
The radii of starlikeness and convexity associated with lemniscate of Bernoulli and the Janowski function, for , have been determined for normaliz…
Lemniscate Convexity and Other Properties of Generalized Bessel Functions
Vibha Madaan, Ajay Kumar, V. Ravichandran
Sufficient conditions on associated parameters and are obtained so that the generalized and \textquotedblleft{normalized}\textquotedblright{} Bessel function $u_p(z)=u_{p…
Starlikeness associated with lemniscate of Bernoulli
Vibha Madaan, Ajay Kumar, V. Ravichandran
For an analytic function on the unit disk satisfying we obtain sufficient conditions so that satisfies T…
