Abstract

We use a new qq-exponential operator based on the q±1q^{\pm1}-derivative \Dq±1\D_{q^{\pm1}} of order 1 to derive summation formulas for bilateral basic hypergeometric series 0ψ1{}_{0}\psi_{1}, 1ψ1{}_{1}\psi_{1}, 1ψ2{}_{1}\psi_{2}, and 2ψ2{}_{2}\psi_{2}. In addition, we provide summation formulas for bilateral series whose terms are basic hypergeometric functions.
