Elliptic hypergeometric functions: integrals versus series (2412.12673v1)

Abstract: The univariate elliptic beta integral is represented as a bilinear combination of infinite ${10}V_9$ very-well-poised elliptic hypergeometric series representing the sum of residues of the integrand poles. Convergence of this combination of series for some particular choice of parameters is discussed. Additionally, the asymptotics of the Frenkel--Turaev sum for a terminating ${10}V_9$ series is considered when the termination parameter $n$ goes to infinity.
