A $q$-continued fraction

Abstract

We use the method of generating functions to find the limit of a qq-continued fraction, with 4 parameters, as a ratio of certain qq-series. We then use this result to give new proofs of several known continued fraction identities, including Ramanujan's continued fraction expansions for (q2;q3)/(q;q3)(q^2;q^3)_{\infty}/(q;q^3)_{\infty} and (q;q2)/(q3;q6)3(q;q^2)_\infty / (q^{3};q^{6})_\infty^3. In addition, we give a new proof of the famous Rogers-Ramanujan identities. We also use our main result to derive two generalizations of another continued fraction due to Ramanujan.
