we apply the better - behaved gkz hypergeometric systems to study toric calabi - yau deligne - mumford stacks and their hori - vafa mirrors given by affine hypersurfaces in algebraic tori. we show the equality between a - brane and b - brane central charges, in terms of period integrals and hypergeometric series respec... | arxiv:2404.16258 |
