  Some Tur\'an type inequalities for Struve functions of the first kind are
deduced by using various methods developed in the case of Bessel functions of
the first and second kind. New formulas, like Mittag-Leffler expansion,
infinite product representation for Struve functions of the first kind, are
obtained, which may be of independent interest. Moreover, some complete
monotonicity results and functional inequalities are deduced for Struve
functions of the second kind. These results complement naturally the known
results for a particular case of Lommel functions of the first kind, and for
modified Struve functions of the first and second kind.
