Geometric properties of generalized Bessel functions of complex order. (English) Zbl 1120.30005

In this paper the author uses method from the theory of differential subordinations in order to receive conditions of univalence, starlikeness and convexity for the generalized and normalized Bessel functions of the first kind of complex order.
