报告摘要:Given a projective conifold transition of smooth projective threefolds from X to Y, we show that if the Gromov–Witten /Pandharipande–Thomas descendent correspondence holds for the resolution Y, then it also holds for the smoothing X with stationary descendent insertions. As applications, we show the correspondence in new cases, especially for Fano threefolds.
