Some Characterizations on the Normalized Lommel, Struve and Bessel Functions of the First Kind

In this paper, we introduce new technique for determining some necessary and sufficient conditions of the normalized Bessel functions $j_ν$, normalized Struve functions $h_ν$ and normalized Lommel functions $s_{μ,ν}$ of the first kind, to be in the subclasses of starlike and convex functions of order $α$ and type $β$.

Certain Geometric Properties of Some Bessel Functions

In this paper, we determine necessary and sufficient conditions for the generalized Bessel function to be in certain subclasses of starlike and convex functions. Also, we obtain several corollaries as special cases of the main results, these corollaries gives the corresponding results of the familiar, modified and spherical Bessel functions.
