On some continued fraction expansions for the ratios of the function

In his lost notebook, Ramanujan has defined the function by \begin{equation*} \rho(a ,~b) := \left(1 +\frac{1}{b}\right)\sum_{n=0}^{\infty} \frac{(-1)^{n}q^{n(n+1)/2} {a}^{n}{b}^{-n}}{(-aq)_{n}}, \end{equation*} where and and has given a beautiful reciprocity theorem involving . In this paper we obtain some continued fraction expansions for the ratios of with some of its contiguous functions. We also obtain some interesting special cases of our continued fraction expansions which are analogous to the continued fraction identities stated by Ramanujan. \end
