        abstract = {M.D. Hirschhorn [10] has shown that Jacobi’s two – square theorem is an immediate consequence of a famous identity of Jacobi.  Motivated by this, we show how several identities of Ramanujan involving Lambert series, product and Quotient of theta functions follows easily from Jacobi’s triple product identity.},
