| Abstract: |
| In this paper we derive finite forms of the summation formulas for bilateral basic hypergeometric series $_3\psi_3$, $_4\psi_4$ and $_5\psi_5$. We therefrom obtain the summation formulae obtained recently by Wenchang CHU and Xiaoxia WANG. As applications of these summation formulae, we deduce the well-known Jacobi's two and four square theorems, a formula for the number of representations of an integer $n$ as sum of four triangular numbers and some theta function identities. |
