Two complementary relations for the Rogers-Ramanujan continued fraction (2112.12081v2)
Published 19 Dec 2021 in math.NT
Abstract: Let $R(q)$ be the Rogers-Ramanujan continued fraction. We give different proofs of two complementary relations for $R(q)$ given by Ramanujan and proved by Watson and Ramanathan. Our proofs only use product expansions for classical Jacobi theta functions.
