Abstract
The main object of this paper is to present a family of \(q\)-series identities which involve some of the theta functions of Jacobi and Ramanujan. Each of these (presumably new) \(q\)-series identities reveals interesting relationships among three of the theta-type functions which stem from the celebrated Jacobi’s triple-product identity in a remarkably simple way. The results presented in this paper are motivated essentially by a number of recent works dealing with the subject matter which is investigated herein.
