Title:
Gromov-Witten invariants of blow ups
Abstract: We describe how the moduli space of holomorphic curves
of the one point blow up \tilde M fits inside the the moduli of
holomorphic curves of M. Moreover it contains enough
information so that the Gromov-Witten invariants of M
can be computed in terms of the Gromov-Witten invariants of
\tilde M.
