Abstract

We study the bb-function with respect to weights of hypergeometric ideals HA(β)H_A(\beta), where AA is an n×(n+1)n\times(n+1) matrix of maximal rank. We describe the bb-function for any weight vector (ω,ω)(-\omega,\omega) with ωRn+1{0}\omega\in{\mathbb R}^{n+1}\setminus\{0\} and any parameter vector βCn\beta\in{\mathbb C}^n.
