摘要：

In 1919, Ramanujan gave the identities Sigma(n >= 0) p(5n + a)q(n) = 5 Pi(n >= 1) (1 - q(5n))(5)/(1 - q(n))(6) and Sigma(n >= 0) p(7n + 5)q(n) = 7 Pi(n >= 1) (1 - q(7n))(3)/(1 - q(n))(4) + 49q Pi(n >= 1) (1 - q(7n))(7)/(1 - q(n))(8) and in 1939, H.S. Zuckerman gave similar identities for Sigma(n >= 0) p(25n + 24)q(n) , Sigma(n >= 0) p(49n + 47)q(n) and Sigma(n >= 0) p(13n + 6)q(n) From Zuckerman's paper, it would seem that this last identity is an isolated curiosity, but that is not the case. Just as the first four mentioned identities are well known to be the earliest instances of infinite families of such identities for powers of 5 and 7, the fifth identity is likewise the first of an infinite family of such identities for powers of 13. We will establish this fact and give the second identity in the infinite family. (C) 2017 Elsevier Inc. All rights reserved.
