摘要

A new sums-of-tails identity involving two parameters b and d is obtained and is used to derive more results of similar type. One of Ramanujan’s sums-of-tails identities from the Lost Notebook is shown to be a special case of our result. In the course of deriving Ramanujan’s identity, we obtain a new result of combinatorial significance. Two new representations for an infinite series associated to a mock theta function are derived. Also, we give an application of an identity of Andrews and Onofri.
