Using the degeneration formula and absolute/relative correspondence,.we study the change of Gromov-Witten invariants under blow-ups for.smooth projective threefolds, and obtain several closed blow-up formulae for.high genus Gromov-Witten invariants. Our formulae also imply some simple.relations among generalized BPS numbers.
