Jackson’s 2ϕ2 transformations over the root systems An, Cn, Dn
摘要
We derive twenty different multivariable generalizations of Jackson’s 2ϕ2 transformation by applying elementary proofs. Then, by reversing the order of summation, we obtain eight multivariable extensions of transformations of terminating 2ϕ1 series. As limiting cases of our main results, we obtain three An1ϕ1 summation formulae.
