Abstract

The main purpose of the present paper is to ascertain the radii of starlikeness and convexity associated with lemniscate of Bernoulli and the Janowski function, (1 + Az)/(1 + Bz) for −1 ≤ B < A ≤ 1, of normalized hyper-Bessel function.


Keywords

Hyper-Bessel function, Lemniscate of Bernoulli, Janowski function.
