Invariance of quantum rings under ordinary flops III: A quantum splitting principle
Yuan‐Pin Lee, Hui-Wen Lin, Feng Qu, Chin-Lung Wang · Cambridge Journal of Mathematics · 2016
In this paper we prove the invariance of quantum rings for general ordinary flops, whose local models are certain non-split toric bundles over arbitrary smooth bases.An essential ingredient in the proof is a quantum splitting principle which reduces a statement in Gromov-Witten theory on non-split bundles to the case of split bundles.
