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 $j_{\nu}$, normalized
Struve functions $h_{\nu}$ and normalized Lommel functions $s_{\mu,\nu}$ of the
first kind, to be in the subclasses of starlike and convex functions of order
$\alpha$ and type $\beta$.
