文摘In this paper, we first prove a vanishing theorem of relative Gromov-Witten invariant of Pl-bundle. Based on this vanishing theorem and degeneration formula, we obtain a comparison theorem between absolute and relative Gromov-Witten invariant under some positive condition of the symplectic divisor.
