Short proofs of the elliptic beta integrals
Abstract
We give elementary proofs of the univariate elliptic beta integral with bases |q|, |p|<1 and its multiparameter generalizations to integrals on the An and Cn root systems. We prove also some new unit circle multiple elliptic beta integrals, which are well defined for |q|=1, and their p 0 degenerations.
