Query: Some inequalities for Kurepa's function   In this paper we consider Kurepa's function $K(z)$ \cite{Kurepa_71}. We give
some recurrent relations for Kurepa's function via appropriate sequences of
rational functions and gamma function. Also, we give some inequalities for
Kurepa's function $K(x)$ for positive values of $x$.
