Abstract

The identities of theta functions θa,b(x, T) for a,b ∈ 1/3Z derived using properties of eigenvectors corresponding to the discrete Fourier transform φ(3). These identities are natural extensions of classical identities of Jacobi theta functions. In particular a quadratic identity and fourth order identity is obtained corresponding to theta functions on 1/3Z.
