A New Proof of Winquist's Identity

Winquist's identity plays a vital role in the proof of Ramanujan's congruence

Two Simple Proofs of Winquist's Identity

We give two new proofs of Winquist's identity. In the first proof, we use basic properties of cube roots of unity and the Jacobi triple product identity. The latter does not use the Jacobi triple product identity.

ON GENERAL SERIES-PRODUCT IDENTITIES

We derive the general series-product identities from which we deduce several applications, including an identity of Gauss, the generalization of Winquist's identity by Carlitz and Subbarao, an identity for [Formula: see text], the quintuple product identity, and the octuple product identity.

Hirschhorn's identities

We prove a general identity between power series and use this identity to give proofs of a number of identities proposed by M.D. Hirschhorn. We also use the identity to give proofs of a well-known result of Jacobi, the quintuple-product identity and Winquist's identity.
