Abstract

In terms of Dougall’s \(_2H_2\) series identity and the series rearrangement method, we establish a symmetric formula for hypergeometric series. Then it is utilized to derive a known nonterminating form of Saalschütz’s theorem. Similarly, we also show that Bailey’s \(_6\psi _6\) series identity implies the nonterminating form of Jackson’s \(_8\phi _7\) summation formula. Considering the reversibility of the proofs, it is routine to show that Dougall’s \(_2H_2\) series identity is equivalent to a known nonterminating form of Saalschütz’s theorem and Bailey’s \(_6\psi _6\) series identity is equivalent to the nonterminating form of Jackson’s \(_8\phi _7\) summation formula.
