Gopakumar-Vafa不变量是定义为Gromov-Witten不变量的某些线性组合的数。证明了一个环形Calabi-Yau三倍形的GV不变量是整数,且高属的不变量消失。积分性的证明基于初等数论,消失性的证明使用算子形式和指数公式。§
The Gopakumar–Vafa invariants are numbers defined as certain linear combinations of the Gromov–Witten invariants. We prove that the GV invariants of a toric Calabi–Yau threefold are integers and that the invariants for high genera vanish. The proof of the integrality is based on elementary number theory and that of the vanishing uses the operator formalism and the exponential formula. §
